6. Set up your Dual SD Memory Card Slots: The two memory card slots of the D7100 can function in a couple different ways, including using one for saving RAW files and the other for JPEG files, saving all your images to both cards simultaneously, using the second card as overflow when the first one fills up, or saving still images to one and movies to the other. You can set this up in the Shooting Menu under Role played by card in slot 2. To set how the cards function for saving videos, use the Shooting Menu > Movie Settings > Destination.

7. Use Picture Styles for your JPEG Images: If you are capturing your images as (NEF)RAW or JPEG files and will be post-processing your images in software such as Photoshop or Lightroom, then you don’t necessarily need to worry about Picture Styles. If that is the case, set the Picture Style for Standard or Neutral so that the images that you view on the camera’s rear LCD screen will be close to how they will appear in the actual RAW image file that you open on your computer. However if you are not post-processing, you will want the images to come out of the camera looking as you want them to, so you will need to set, customize, or create a Picture Style that best creates your desired look. Adjust the contrast, saturation, sharpening, etc. to achieve the look you are after. Save the Picture Styles you have created to access them later. You can even create your own styles using the included software, or find them online and download them. There are even styles to be found online that recreate the look of various traditional types of film including Kodachrome and Velvia.

8. Customize the Exposure Compensation Controls: Exposure Compensation can be used to adjust the camera’s exposure settings in order to achieve the final exposure that you desire. Explore the various options of Custom Setting b3: Easy Exposure Compensation to customize exactly how the exposure compensation (EC) controls works. You can set it so that you press the Exposure Compensation Button first before turning a dial to change EC, or have it set so that you can just turn a dial to quickly and directly change EC. You can even select which dial you use with Custom Setting f5. And you can set it so that the EC amount that you dialed in stays set for the subsequent shots, or that it is automatically reset to zero, depending on which controls you choose to use to set EC. This last option is the most sophisticated and most flexible, and may be the best one to learn and take advantage of. Using this option, On (Auto reset), you can choose to turn a dial to directly adjust EC, but your EC setting will be reset when the camera or exposure meter turns off. This is because you can still continue to use the Exposure Compensation Button with a Command Dial to set EC, but by setting it this way, EC will not be reset when the camera or meter turns off. Exposure Compensation will only be automatically reset if you set it directly using the dial without the button. So if you wish to use EC for just one shot, you can adjust EC with just the dial. But if you wish to take a series of shots with the same adjusted EC, you can use the button/ dial combination to set it more “permanently.” Pretty powerful stuff! This is why you got the D7100, right? So that you can take advantage of these sophisticated controls!

9. Fine-Tune the Exposure Metering Modes: While the Matrix Metering Mode will do an excellent job of determining the proper exposure for your images the majority of the time, there are some situations where you may wish to use the other exposure modes – Center-Weighted Metering and Spot Metering. This includes dramatically backlit situations, subjects with a dramatically dark background, scenes that contain a wide range of highlights and shadow areas, or other dramatic lighting situations.

If you find that you are consistently not quite happy with how the camera’s meter is determining the exposure settings when making use of any of these modes, you can make fine-tune adjustments to the metering system using Custom Setting b5: Fine-tune optimal exposure. This is not an exposure compensation adjustment, but rather a “behind the scenes” fine-tuning of how the camera’s meter will determine the exposure settings, independently for each of the different Exposure Metering Modes (Matrix, Center-Weighted Average, Spot). If you find that your images are always typically being slightly underexposed or overexposed when using a specific metering mode, adjust this accordingly so that you don’t have to use exposure compensation every time you use that metering mode. For example, you may find that Center-Weighted Metering delivers great exposures, but you would prefer that the images taken with Spot Metering were 1/3 EV (1/3 step) underexposed all the time. If that is the case, you would adjust Spot metering to -2/6 using this menu. If you make use of this fine-tune adjustment, you can still use exposure compensation in any situation in addition to this fine-tune adjustment.

Fine-tuning Spot Metering to underexpose by -1/3 EV (right) – not recommended, just an example!

10. Put Your Most Used Settings in My Menu: Instead of navigating into the Menus and Custom Settings all the time to find your most used settings, you can create your own custom menu called My Menu, which is then quickly and easily accessed with the Menu Button. You can even decide what order to list the items in. Set up My Menu by selecting Choose Tab in the Recent Settings menu, and select My Menu. Then Add Items and Rank Items in the order you desire. You can add items from most all of the Menus and Custom Settings Menus, such as maybe Movie Settings, some of the Flash control settings, or White Balance for easier access to additional white balance options and fine-tuning. If you frequently make use of a feature such as changing the Image Area from DX to 1.3x, use Interval Timer Shooting, or Multiple Exposures add these to your My Menu.

As you are likely discovering with your Nikon D7100, it is a highly customizable and versatile camera, and there are a lot of Menu options and Custom Settings that you can make use of in order to fine-tune the camera to perfectly fit your needs, shooting style, and scene or situation. The autofocus system and exposure metering system can be adjusted according to your needs and desires, the camera controls can be customized and assigned to a variety of functions, the displays, White Balance, and ISO can be tweaked according to your preferences. I’ve spent a considerable amount of time with the D7100 as I researched and wrote my e-book user’s guide to the D7100 called Nikon D7100 Experience, and below are the some of the top “tips and tricks” I’ve discovered for setting up and photographing with this powerful dSLR.  I previously put together a similar “D7000 Tips and Tricks” post for the Nikon D7000, and all of those tips apply to the D7100 as well.  I have repeated a couple of the important ones, and added several new ones here (in no particular order). Since this has turned into such a long post, I am dividing into two parts (Part 2 coming soon…)

1. Take Control of the D7100 Autofocus System: Before getting into some of the tips regarding features and functions specific to the D7100, one needs to first take control of the basic functions of the camera, including the autofocus system and exposure metering settings. The D7100 boasts a 51 point autofocus system, upgraded from the 39 point system of the D7000. The large number of focus points and their positions in the Viewfinder will allow you to focus exactly where you wish – with minimal recomposing (when working in Single-Servo AF-S mode), plus will better enable you to track moving subjects throughout the frame when working in Continuous-Servo (AF-C) autofocus mode. The various autofocus modes (AF-S, AF-C, etc.) and the autofocus area modes (Single Point, Dynamic Area, etc.) may be intimidating at first, but once they are understood, it is easy to determine which combinations fit your shooting needs. Despite the increase in AF points, the system works nearly the same as that of the D7000, and I wrote an entire post introducing the use of the Nikon autofocus system, its AF and AF-Area modes, and its controls. If you have not previously used the D7000 or D600 you may at first be confused by the autofocus controls with the AF switch / button near the base of the lens (used in conjunction with the Command Dials), but you should quickly find that it is a quick and convenient way to change the AF modes and AF area modes.

In addition, the D7100 offers several Custom Settings to customize various aspect of the autofocus system, namely Custom Settings a1-a6. You can use these to tell the camera if achieving exact focus takes priority over maintaining the fastest continuous frame rate, how long the AF system continues to track a specific subject (distance) even if the subject momentarily moves away from the active AF point, and if the active AF points are illuminated in the Viewfinder. You can even limit the number of selectable AF points to 11 if that helps you to more quickly or easily select your desired AF point. Each of these options are explained in my previous Nikon AF system post mentioned above.

2. Take Advantage of the new [i] Button: The D7100 adds the [i] Button (on the rear of the camera) which gives you immediate access to the Information Display screen, where many shooting settings and functions can be viewed and changed. You can press this button to turn on the Information Display on the Monitor and immediately access these settings with the use of the Multi Selector and OK Button. Press the [i] Button a second time or the Info button to “de-activate” the settings and simply view the camera settings on the Information Display Screen. Or, after the Info Button is pushed to display the camera settings of the Information Display screen on the rear Monitor, this [i] Button is pressed to “activate” the screen to enable changing the settings. In addition to the readily accessible camera buttons on the body of the D7100, this [i] Button and Information Display screen can be a quick and easy way to change many of the camera settings without having to dig into the menus, such as Image Area, Active D-Lighting, High ISO Noise Reduction, and Long Exposure Noise Reduction. Plus you can use this screen to quickly access and customize the DOF Preview Button, AE-L / AF-L Button, and Fn Button Assignments.

The [i] Button can also be used during Live View shooting, Movie shooting, and Image Playback – to quickly access a number of applicable functions.  During Live View shooting it can be pressed to access settings including Image Area, Image Quality, Image Size, Picture Control, Active D-Lighting, Remote Control Mode, and Monitor Brightness. During Movie shooting, the [i] Button will access Image Area, Picture Control, Monitor Brightness, Frame Size and Frame Rate, Movie Quality, Microphone sensitivity, Destination for which SD card slot movies will be saved to, and Headphone Volume. Plus during video playback, the [i] Button is also used to display movie edit options. When reviewing images during Image Playback, the [i] Button will access the Retouch Menu, which will allow you to apply various image edits such as Color Balance, Filter Effects, and Distortion Control.

3. Beware of Menu Conflicts: As with most current dSLR cameras, the D7100 has a couple menu settings and function “quirks” or conflicts that may drive you crazy if you are not aware why they are occurring. Most notably, some settings will be greyed-out or inaccessible in the menus and you will not be able to select them when working in one of the auto shooting modes, if not using an optional accessory, or if a “conflicting” setting is enabled. An example includes HDR shooting, which is not accessible when the camera is set to capture files in the (NEF) RAW or (NEF) RAW+JPEG image formats. Or, since White Balance Bracketing and RAW format are incompatible, if the camera is set for White Balance Bracketing and (NEF) RAW or (NEF) RAW+JPEG image formats, the BKT Button will not allow you to access bracketing. These are actually not arbitrary quirks, but are typically logical conflicts.

Custom Setting f2: Assign Function (Fn) Button, with the “Press” and “Press+Command Dials” options. Some of the “Press” options shown at right.

Another set of conflicts involves the customization of some buttons (Fn Button, Preview Button, and AE-L/AF-L Button) where you have the option to set a separate Press function (where you simply press the button) and a Press+Dial function (where you press the button and turn a dial in order to change a setting). While it at first seems handy that the D7100 menus separated the Press from the Press+Dial functions thus allowing you more options, you will soon find that most of them conflict, and in reality you will likely only be able to set either a Press function or a Press+Dial function.

4. Extend Your Reach with the 1.3x Crop Mode: Just as the D600 allows you to shoot in either full-frame FX mode or in a cropped DX mode, the D7100 allows you to shoot in full-sensor DX mode or in a cropped 1.3x mode. Using the Image Area menu setting, you can set the D7100 APS-C sized DX format sensor to act as an even smaller sized sensor, with an additional 1.3x crop. While the default DX setting takes advantage of the entire sensor, by enabling the 1.3x crop setting you can change the aspect ratio (very slightly) and angle of view (dramatically) of your resulting images – basically cropping your photos from what you see in the full Viewfinder to what you see inside the 1.3x outline shown in the Viewfinder when this feature is enabled.

Location of all the Focus Points shown for reference. The 1.3x crop will, in effect, allow you to extend the reach of your lens and get closer to the action, as well as nearly fill the width of the active frame with the Focus Points.

The first advantage of the 1.3x crop is that it will allow you to “get closer” to the action by virtually extending the reach of your lenses. This can be particularly helpful when using a telephoto lens to capture sports, wildlife, or bird images where the subject is at a significant distance from you. It will allow, for example, your 200mm focal length lens to act as nearly a 400mm focal length. (Since the DX frame is already a 1.5x crop sensor in relation to a full-frame 35mm sized sensor, the additional 1.3x crop effectively doubles the focal length of the lens: 200mm X 1.5 X 1.3 = 390mm.)

The second advantage is that with the 1.3x crop, the area of the autofocus points as seen in the Viewfinder reaches nearly to the sides of the effective frame. This will allow you to track and capture a moving subject throughout almost the entire width of the active frame (when using continuous AF-C Focus Mode), or enable you to focus on and capture a still subject most anywhere in the frame without having to lock focus and reframe (when using single-shot AF-S Focus Mode).

A third advantage of working in 1.3x crop mode is that the Continuous High shooting speed goes from 6 fps to 7 fps (when shooting in JPEG or in 12-bit NEF-RAW), allowing you to capture slightly more images in a quick burst.

The disadvantage of the 1.3x crop is that you will only be using 15 megapixels of your 24.1 megapixel sensor, so you will have slightly reduced image resolution. The end result will be as if you cropped the image in post-processing. However, 15 MP is still a very high resolution, and for many shooting situations and image needs this may be more than sufficient.

5. Interval Timer and Time-Lapse Shooting: The Interval Timer Shooting function can be used to take a continuous series of photographs at each specified time interval, for a set number of intervals, with the intervals to begin either immediately or at a set time. It can be used to take these multiple series of shots over several minutes or hours – for example, 3 photos in a row every 10 minutes, for 12 intervals. This will result in a total of 36 photos, as the camera will calculate and show you. This Interval Timer Shooting menu can also be used for time-lapse photography by taking a series of individual photos over an extended period of minutes or hours, with just one photo per interval, which can then be combined into a time-lapse movie (using software designed for this such as Photoshop).

Nikon D7100 book manual guide how to tips tricks interval timer time lapse setting menu quick
Interval Timer Shooting menus. Left: Setting the Interval time period between shots, here set for 10 minutes. Right: Setting the number of intervals and the number of shots to be taken at the start of each interval. Here, 12 intervals are set, with 3 shots to be taken each interval, for a total of 36 shots. The intervals are to start immediately, with the time between intervals as 10 minutes. The current time is 16:17 (which is shown in case you wish to set the Start Time).

Use the Interval Timer Shooting menu to choose all of your desired settings. Ideally, set up your camera on a tripod for the duration of Interval Timer Shooting, and use the included Eyepiece Cap to cover the Viewfinder and prevent stray light from altering the exposure. The camera will need to focus before taking the shots, so it may be best to pre-focus the camera and then set the camera and lens to manual focus.

For time-lapse photography you will need to take images at short intervals, with just one image per interval, for numerous intervals, in order to create a long and effective movie. For example, a photo every 30 seconds, for 8 hours. Be sure to have a large memory card or cards in the camera, and set the Role Played by Card in Slot 2 for Overflow if necessary. In the software you will set the movie frame rate, and that setting (24fps, 30fps, etc.) will determine to total length of the movie. There are time-lapse formulas, as well as apps, which you can use to plug-in your variables and determine either the settings you will need to use, or the resulting length of the final movie.

Here is a link to a tutorial for creating a time lapse movie using Photoshop. There are also plug-ins/ templates for Lightroom which will allow you to assemble and export a time-lapse video using that software (direct link to presets zip file).

I’ve had some hands-on time with the new Nikon D7100 as I research and write my latest camera guide Nikon D7100 Experience, and just as with the recently introduced Nikon D600 this new model does not disappoint. In fact, much of what I’ve said about the D600 will apply to the D7100, as in many ways the D7100 is basically a D600 but with a DX sensor (rather than the full frame FX sensor of the D600). Of course there are some important differences (in addition to the image sensor size) such as the 51 point autofocus system and slightly faster 6 frames per second shooting speed of the D7100, but the feel, performance, features, menu system, and Custom Settings of the two cameras are quite similar.

The Nikon D7100 Unboxing – shown here with a Nikon 18-200mm f/3.5-5.6 lens attached, not the 18-105mm f/3.5-5.6 kit lens.

The D7100 is a worthwhile and timely upgrade to the popular and well-respected D7000. The new model boasts an improved 24.1 megapixel DX format image sensor (vs. 16MP of the D7000), a sophisticated 51 point autofocus system with 15 centrally positioned cross-type points (vs. the older 39 point system with 9 cross-type points), the rapid 6 (or even 7) frames per second continuous shooting speed, and a larger and higher resolution 3.2″ rear LCD screen. All of these features make it particularly well-equipped for action and movement situations including sports, wildlife, and bird photography.

With this new image sensor, Nikon has done away with the optical low pass filter – a choice which promises to deliver higher image resolution (though at the risk of increased moiré when capturing fine pattern details). And its high ISO capability will result in decreased digital noise in low-light situations. The new, optional 1.3x crop mode of the D7100 will allow you to use a 15 megapixel portion of the sensor to “extend” the reach of your telephoto lenses in order to get closer to the action as well as fill the active frame with the 51 Focus Points – in order to more accurately track moving subjects across nearly the full width of the frame. And the continuous shooting speed even increases from 6 frames per second (fps) to 7 fps when working in this 1.3x crop mode. Plus when capturing video using the 1.3x crop Image Area, you can choose from the additional 1080 frame size at 60i or 50i frame rates.

As with its predecessor, the Nikon D7100 is aimed at intermediate and dedicated enthusiast photographers (and dSLR beginners willing to learn!), not only with its price and build, but also with its features and accessible controls and menus. It is obviously not quite as fully-featured as the professional-level D800 or D4, yet it contains nearly every feature that the majority of “non-pro” or even semi-pro photographers will need. And its low light performance and image quality can certainly deliver professional results in most every shooting situation.

As the author of dSLR user guides, my primary interest when reviewing a camera is more with the controls, features, functions, and “real world” use – as opposed to the image quality/ sensor issues (resolution, dynamic range, noise, etc.), which I leave up to DP Review, DXOMark, and other sites to examine in depth. Although I will discuss and give examples of some of these factors in this post, I direct you these other sites to view samples/ comparison images and read detailed discussions of sensor and image quality results.

Body: Weight and Size: The D7100 is nearly identical in size and weight (765 g / 1.7 lb w/ battery) to the D7000. It is of course bigger and heavier than the mid-level D5200, but is an excellent size for the serious shooter – and pairs excellently with a wide range of lenses from a 50mm f/1.4 prime to the hefty 70-200mm f/2.8.

Body: Controls and Feel: The controls of the D7100 are very similar to the D7000, and even more similar to the D600. If you have not yet used either of those previous cameras you may be initially confused by the autofocus controls at the base of the lens, including the AF-Mode Button and the Focus-Mode Selector Switch. However, once learned you will quickly discover that they are a convenient, well thought-out set of controls for rapidly accessing and changing the various autofocus settings – even without taking your eye from the Viewfinder.

Detail of the front controls of the Nikon D7100, including the autofocus mode and area mode controls at the base of the lens.

Compared to the D7000, the D7100 adds an i Button to the rear of the camera, which is used to quickly access a variety of settings and options – which will vary based on if you are shooting stills, reviewing images, working in Live View, or in movie shooting. During shooting it allows you to access the Information Display screen where you can change a number of settings that you otherwise would have had to dig into the menus to find. This is similar during Live View and movie shooting, but accesses settings appropriate to those modes.  During image playback, the i Button quickly brings up the Retouch Menu for editing and processing image files.

The placement of the zoom-in and zoom-out buttons on the rear of the D7100 has been swapped compared to the D7000, which may drive you crazy until your muscle memory is retrained.  But the new rear Live View / Movie switch, the relocation of the video record button to the top of the camera near the Shutter Button, and the locking Mode Dial are welcome conveniences (which I prefer as there have been many times my Mode Dial was accidentally turned when pulling the camera out of its bag). Other than that, D7000 users should feel right at home with the controls such as the Release Mode Dial for selecting the frame rate and the Playback and Delete Buttons. And the consistency of layout between the D7100 and the D600 is a welcome move from Nikon – which hopefully continues into future models. The Multi Controller thumb-pad is responsive and precise, which is necessary when using it to select among the 51 autofocus points or to quickly navigate and change a menu settings. And the rubberized feel of the Command Dials is much nicer to the touch than the plastic feel of lower-end models.

Some of the top and rear controls of the Nikon D7100, including the Release Mode and locking Shooting Mode Dials, and new i Button.

A few of the buttons along the left side of the camera perform additional functions when pressed and used in conjunction with the Command Dials.  These are handy to learn and use so that you can quickly change these settings on the fly, though you will likely need to glance at the buttons to recall which function it performs. (And I would prefer that the WB, QUAL, and ISO text be a bit closer and adjacent to the appropriate button, as you can see one needs to often take a second look to see of ISO applies to the button below or above.) So, for example, the QUAL Button is pressed as the rear Main Command Dial is turned to select the Image Quality (JPEG / RAW), and it is press as the front Sub-Command Dial is turned to select the JPEG Image Size (S, M, L).

In addition to the previous customization options for the controls as found on the D7000 and D600, the D7100 offers even more custom controls. For example during image playback, the OK Button can be set up to instantly zoom in on the image at the area of focus, and you can even set the magnification level for high, medium, or low. You can set the OK Button to perform other functions during shooting and Live View, though I recommend that it be used to quickly select the center AF Point. The Fn Button and Depth of Field Preview Button can be customized to perform different functions when just pressed and when pressed and used with a Command Dial.  For example, you can set one of these buttons for quick, temporary access to Spot Metering Mode or to display the Virtual Horizon in the Viewfinder. Or you can press the button as you turn the Command Dials to quickly change to 1.3x crop Image Area Mode or to activate HDR shooting and set the HDR Mode with one dial and HDR Strength with the other.  Unfortunately, there are a lot of conflicts between the just Press and the Press+Dial settings which allow you to actually use only one of the options, so you will likely only be able to set each button for one function. I suggest setting the AE-L/AF-L Button to lock focus, the Fn Button to lock exposure, and the DOF Preview button to the function of your choice.

Example of one of the button customization options – assigning the Fn Button for use with a Command Dial.

The new Live View Selector switch is used to quickly choose between Live View and movie shooting, then the central LV Button is pressed to enter that mode. Again, the Movie-Record Button is now on the top near the Shutter Button.

I found the Shutter Button to be less sensitive than that of the D7100, which is a welcome change, as I often accidentally took a picture when simply trying to lock focus with the D7000 – though this change could simply indicate that I have gotten used to controlling the more sensitive button.

Overall, the body size, weight, and materials feel great and solid, and all the necessary and desired buttons and controls are in the right places. As with the D600, this results in a camera that I find a joy to use with the easy ability to access a wide variety of settings and functions.

Brief Commercial Interruption: I have written an e-book guide to the Nikon D7100, called Nikon D7100 Experience. The guide covers all the controls, functions, features, Menus options and Custom Settings (with recommended settings), autofocus system, exposure, metering, and more. Plus most importantly, it explains how, when, and why to use the various controls, features, and functions of the D7100.

Use and Response: There really isn’t too much else I can say about the D7100 in action, as it performs excellently, as expected. The autofocus response is quick and accurate in normal use, and able to lock on quickly and accurately even in dim lighting. Note that the 15 central AF Points are cross-type points, which you will want to make use of in low light and challenging focusing situations. (This means that these points look for contrast in both the horizontal and vertical orientation, and thus can more easily and quickly find contrast to focus on.) In low light, night-time scenes – such as the in-camera Multiple Exposure image and the in-camera HDR image below – the camera locked right on and focused well.

Autofocus System: As with the D7000, the autofocus system of the D7100 is one of its most important features, and you will need to learn to take control of it in order to get the most out of the camera. This means choosing the appropriate Autofocus Mode and Autofocus Area Mode, depending on if the subject is still or moving. I go into detail on this in an article about Taking Control of the  D7000 Autofocus System. While the D7100 of course offers 51 autofocus points rather than 39, the exact same principles apply – you simply have more AF points to help you compose the image exactly how you wish or to help you more accurately track a moving subject throughout the frame. And if 51 autofocus points are too many to deal with at first or in a specific situation, you can limit the number of selectable Focus Points to 11 in the Custom Settings menu.

I briefly did some testing of the AF system using AF-C Focus Mode for tracking moving subjects using 9-Point Dynamic Area AF Autofocus Area Mode, while shooting bursts of images in Continuous Shooting release mode. With the Dynamic Area AF modes, you select your desired AF Point to begin tracking the subject, and the surrounding points are used to help retain focus on the subject if it briefly leaves the active AF point.  You can choose from either 9 additional “helper” points, 21 points, or all of them.  Since I was tracking a relatively easy-to-keep-track-of running dog, I selected 9-Point. I placed the selected point on the dog, pressed the shutter button half-way to begin tracking the subject distance, then held it down as the camera took a continuous burst of shots. The camera had no trouble keeping focus on the dog as it ran about, even when it momentarily left the active point and was therefore picked up by a surrounding point.

Functions and Features: The D7100 has all the features of the D7000, adds the newer features introduced on the D600, and offers a couple more. There is the in-camera HDR Mode, Multiple Exposure Mode, Interval Timer and Time-Lapse Photography shooting, AF Fine-Tune to microadjust the focusing of individual lenses, in-camera Noise Reduction features, and the in-camera image editing and processing features. The camera can auto bracket for exposure (or flash exposure, white balance, or Active D-Lighting) either 2, 3, or 5 shots, in EV steps from 0.3 to 2 EV – which can greatly assist those capturing shots to combine into a true HDR image. The bracketing variables are easily set with the BKT Button on the front of the camera and the Command Dials, and offers a wide range of options such as shooting all the exposures in a positive or in a negative exposure direction, rather than simply an underexposure and overexposure surrounding 0. For example, with the +3F setting, the first exposure is taken at 0 (the correct exposure), the second at +1 and the third at +2, rather than the typical bracketing sequence of 0, -1, +1.

The new addition to the D7100 is the 1.3x crop mode Image Area, which will allow you to virtually extend the reach of your telephoto lenses by using a smaller 15MP portion of the sensor. While it is basically the same as cropping your photo after the fact, it offers some advantages such as nearly filling the width of the frame with the autofocus points. This will allow you to more accurately track a moving subject throughout most of the active frame, as there will likely be an AF Point to focus on the subject no matter where in the frame the subject is located. Plus in this mode, you can increase the High Speed Continuous shooting speed to 7 frames per second. Since the APS-C sensor of the D7100 is a 1.5x crop of a full frame sensor, the additional 1.3x crop will basically double the focal length of your lens, meaning a 200mm lens will act as a 200 X 1.5 X 1.3 = 390mm lens.

As with previous models of this level, the D7100 allows you to use the built-in flash as a Commander flash, to wirelessly remotely control and trigger up to 2 groups of optional external Speedlights. The D7100 also works with a wide variety of optional accessories such as:

Nikon WU-1a Wireless Mobile Adapter which can be used to wirelessly transmit your images to a tablet or smart-phone as you shoot, share your images, or even use your smart phone or tablet to remotely release the camera’s shutter – all with Nikon’s Wireless Mobile Adapter Utility app.

Nikon GP-1 GPS Unit: Use this GPS receiver for automatic geotagging of your images including location, altitude data, and UTC time.

Nikon ML-L3 Wireless Remote Controller or WR-R10/ WR-T10 Wireless Remote Controller and Transceiver: These wireless remotes will allow you to trigger the shutter of the camera remotely, thus allowing either self-portraits or the ability to release the shutter without pressing the Shutter Button thus preventing possible camera shake. The WR set communicates via radio frequencies, and thus does not require direct line-of-sight between the camera and the remote. You can even use multiple WR-R10 receivers on multiple cameras and trigger them simultaneously with one WR-T10 remote transmitter. The new WR-1 Wireless Remote Controller will allow even greater wireless control over one or multiple cameras with their own WR-1 or WR-R10 unit.

Additional Nikon D7100 Accessories can be seen here.

Menus and Custom Settings: The Menus and Custom Settings of the D7100 allow you to personalize the camera controls and functions to work best for you and your needs and shooting style. They are a powerful set of options, and you should carefully set them up and then review them occasionally to see if they can be tweaked to better suit your current needs. For example, you can customize the size of the area metered by the camera when using Center-Weighted Metering. This can be the default 8mm circle, or else a 6mm, 10mm, or 13mm circle. You can modify the roles of the two memory card slots so that the second one acts as either overflow when the first card fills, simultaneous back-up of the first card, or JPEG on one and RAW on the other. And you can manually copy images from one card to the other. You can set the Continuous Low frame rate anywhere from 1 to 6 fps, though you may find that since Continuous High is 6 fps, 3 or 4 fps should work well. This is a wonderful option that Canon has yet to adopt on its cameras of this level. As mentioned earlier, you can customize the functions of various buttons, and there are numerous other adjustments to the controls and camera functions that you can make. I go though all of these Menu and Custom Setting options in my guide Nikon D7100 Experience, along with recommended settings for various uses.

A relatively new feature in Nikon dSLRs in the additional control over Auto ISO. If you do not wish to worry about the ISO setting and would prefer that the camera takes care of that, you can enable Auto ISO and then the camera will automatically change your selected ISO, without your expressed permission, in certain situations in order to obtain a proper exposure. For example, if you are working in Aperture-Priority Auto Mode (A) and set the ISO at 800, but based on your selected aperture and the lighting the camera does not believe there is enough light for the exposure and a realistic minimum shutter speed (that you can also set in this menu item), it will automatically raise the ISO so that the shutter speed does not become impossibly slow for hand-holding. You can tell the camera the Maximum Sensitivity or maximum ISO that the camera will use in these situations as well as the Minimum Shutter Speed that you would like the camera to automatically use. Alternately, you can choose to leave the Minimum Shutter Speed set for Auto. The great advantage of this setting is that the camera will now select an Auto ISO setting based on the focal length of the lens being used. This is helpful because longer telephoto lenses typically require faster shutter speeds to prevent hand-held camera shake (which will result in blur). In addition, if you find when using this Auto setting for the Minimum Shutter Speed that the camera is still selecting shutter speeds that are slower than you wish (and thus possibly causing blur due to camera shake), you can use this menu to fine-tune this setting and instruct the camera to select a faster Auto shutter speed. So as you can see, it becomes much more viable to make use of the Auto ISO setting of the D7100 and you can still rely on the camera to not alter the settings beyond your desired parameters.

There are a couple functions that will be greyed-out in your menus if you have a certain conflicting setting option set. For example, some features will not be available (like HDR Mode) if you have the image quality set for RAW or JPEG+RAW. You will have to switch to JPEG only in order to access these features. This is bound to aggravate you at first as you try to determine why the function is greyed-out and not accessible in the menus.

Image Quality: I am not a pixel peeper but rather more of the “just get out there and shoot” variety, and I believe that most all the current consumer cameras – including the D7100 – offer more than enough in terms of image quality and low noise for most every photography from enthusiast to semi-pro. So I will leave it up to DP Review, DXOMark, and other sites to evaluate the image quality and sensor performance. I have shot some informal ISO tests, which can be viewed on Flickr, such as the image below:

Video: As noted above, the D7100 offers all the usual frame sizes and rates, including now 1080 frame size at 60i or 50i frame rates when working in the 1.3x crop mode. It has a built-in stereo microphone plus the ability to use an optional external mic, and offers manual audio control. As with all Nikons, there is manual control over the exposure settings, but you have to set the aperture before going into Live Mode movie shooting. The D7100 now offers a headphone jack for monitoring audio and you can control its volume. As noted above, you can use the new i Button to quickly access and change various video related settings before starting to record.

Conclusion: Overall I found the D7100 to be an excellent camera in all areas: handling and feel, build, features, use, controls, and image quality. It is an excellent value for the price, and offers all the controls and features (and then some) that most any enthusiast or semi-pro photographer would need in most any shooting situation.  There really aren’t any shortcomings to this camera (unless the lack of an anti-aliasing filter will affect the types of photos you take). My only minor gripes are the labeling of the left-rear buttons that I mentioned, and the long, scrolling menus that Nikon uses. I definitely prefer the additional menu tabs of the Canon menus that eliminate scrolling menus.

The D7100 should meet or exceed the needs of dedicated enthusiasts shooting any type of images – landscape, portraits, travel, low-light, etc., and is particularly well suited for action, wildlife, and sports photography due to its wide array of 51 autofocus points, fast shooting speed, and 1.3x crop ability to extend the reach of your telephoto lenses. Its sensor, image quality, and capabilities will certainly provide anyone with the potential to not only take professional quality images, but in most situations to capture exactly the image you intend. And that, in the end, is one of the top goals of photography!

This was originally written for the Nikon D7000, but as the Nikon D7100, the Nikon D7000, the Nikon D610 / D600, the Nikon D810 / D800, and the Nikon D5200 / D5300 all share a similar Autofocus system, most of this information will apply to all of them.  And even though some of the models have 51 AF Points instead of the 39 AF Points of the other cameras, all the same settings and actions apply.

The Nikon D7100, the Nikon D7000, the Nikon D610 / D600, the Nikon D810 / D800, and the Nikon D5200 / D5200 dSLRs all share very similar, and quite sophisticated autofocus systems – especially if you are coming from a D90, D5100, or earlier camera.  With their 39 AF points or 51 AF points that can be used independently or together in a variety of ways, its Autofocus Custom Settings that affect many of the functions of the AF system, and the three different Autofocus Modes that are used in various combinations with the four different Autofocus AF-Area Modes, it is no wonder that users are having difficulty figuring it all out. (Plus the D810 offers an additional Group Area AF Area Mode!)

Some of the Autofocus controls of the Nikon D600, located near the base of the lens (to the left of the FX badge and below the Lens Release Button).

First, the Autofocus Controls on the D810/ D800, D610/ D600, D7100, and D7000 are a bit different than previous cameras.  You can change the Autofocus Mode and AF Area Mode by pressing the AF Mode Button (located inside the Focus Mode Selector switch) and then use the Command Dials to adjust the settings as you view them on the top LCD Control Panel or in the Viewfinder.

Focus Mode Selector – This switch is used to turn on or off autofocus. Set to AF for autofocus and M for manual focus. Be sure to set the similar switch on the lens as well. If your camera does not seem to be autofocusing, be sure to check this switch and the one on your lens.

AF Mode Button – This button, located inside the Focus Mode Selector switch, may be confusing at first to those who have not previously seen or used it on the Nikon D7000 or D600, though you should quickly find that it is a convenient design. It is used to select the Focus Mode as well as the autofocus AF-Area Mode. Press this button and turn the rear Main Command Dial to select the Focus Mode, such as AF-A or AF-C, while viewing the setting on the top Control Panel or in the Viewfinder. Press this button and turn the front Sub-Command Dial to set the AF-Area Mode, such as Single-Point AF or 39-Point Dynamic-Area AF. Again, you can view the selected setting on the top Control Panel or in the Viewfinder. The autofocus system including the Focus Modes and AF-Area Modes will be explained below.

Next you will need to set up some of the autofocus Custom Settings to begin to customize how the AF system functions for your needs (Some of these options may not be available with the D5200):

AF-C priority selection – This setting determines if attaining focus is top priority when you are in Continuous-servo AF (Auto-Focus) Mode (AF-C), or if you just want the shots to be taken even if exact focus is not attained for each shot.  If exact focus is your priority, set on Focus.  If getting the shots at all costs is the priority, set for Release.

AF-S priority selection – This is similar to above, except that this setting is for when you are working in Single-servo AF Mode (AF-S), typically used when your subject is not moving.  Since AF-S is typically used with subjects that are not moving, it makes more sense to make sure focus is attained, thus you should typically select Focus for this setting.

Focus tracking with lock-on – This setting determines how the autofocus system reacts to sudden, dramatic changes in the distance of the subject when you are working in AF-C or AF-A modes.  Decide if you wish to have the camera quickly refocus on a new or closer subject (1-Short), wait awhile until it ideally picks up the intended subject again (5-Long), somewhere in between, or immediately refocus on a new subject at a large distance from the initial subject (Off).  Keep this option in mind with the various AF-C and AF Area Mode configurations, as it may change depending on your subject and situation.  Sometimes you don’t want the camera to quickly refocus on a closer or more distant subject, while other times you do.

AF point illumination – This is used to set whether or not the selected autofocus point (AF Point) is illuminated in the viewfinder.  Since you pretty much always want to know where your camera is focusing, this should be set for On.

Focus point wrap-around – This determines if the AF Point selection will “wrap around” to the other side of the screen when you reach an edge.  In other words, if you are selecting your AF Point (as you should be doing at almost all times) and you reach an AF Point on the far right, when you click right again, do you want to “wrap around” to a focus point on the far left, or do you wish to stop at the edge and not continue to the other side?

Number of focus points – This setting determines the number of autofocus points that are available for selection in your viewfinder.  If you are always selecting your AF Point (as you typically should) you may find that it is quicker and easier, at least at first, to limit the number of AF Points to 11 – AF11.  If you prefer to have all the AF Points available for your selection, set this at AF39 (or AF51 with the D7100).  If you set to 11 AF points your selection will be limited to those 11 AF points, but the additional surrounding AF points will still be active to be used by the camera in the AF-Area Modes and in subject tracking, so the camera is still taking advantage of all the AF points of the autofocus system.

Built-in AF-assist illuminator – This is used to enable or disable the autofocus assist light.  Turn this On to assist you in autofocusing in low light, but be sure to turn it Off if you are working in situations where it will be distracting, unwanted, or unnecessary.


Assign AE-L/AF-L button (f4 on the D600 and D7100) – This is to assign the function of the AE-L/AF-L Button.  You may want to use this in conjunction with the Function or Fn Button and use one to lock exposure and the other to lock focus.  In that case, you would typically set this to AF lock only to use this button to lock focus.

I go into much more detail about each these Custom Settings, how you may wish to set them up, and recommended settings in my e-book guides for all the current and previous cameras including Nikon D600 Experience, Nikon D7100 Experience, and Nikon D5200 Experience – but this should get you started.

Using Autofocus
Now on to using the AF system.  (All of the information below is also adapted from my e-book user’s guides, so I hope you will have a look at them to learn more.)

One of the essential steps in taking a successful photo is controlling where the camera focuses.  If you allow the camera to autofocus by choosing its own Focus Point(s), it typically focuses on the closest object or a person in the scene.  This may or may not be what you want to focus on.  So you should choose where the camera focuses using the autofocus Focus Points.  But first you will need to select an appropriate Autofocus Mode and an Autofocus Area Mode, based on your subject and situation.

Autofocus Modes
The D7100, D7000, D600, and D5200 each have three different Autofocus Modes to choose from, typically depending if your subject is still or moving.  They also have four different Autofocus Area Modes (see below) to specify how many of the AF points are active and how they track a moving object.  You can set these two functions in various combinations.  First the Autofocus Modes:

Single-Servo AF (AF-S)
Use this mode when your subject is stationary, or still and not going to move, or if your subject is not going to move very much, or if the distance between you and the subject is not going to change between the time you lock focus, recompose, and take the shot.  Lock focus on the subject and recompose if necessary.  When using AF-S, you can select from two Autofocus Area Modes, either Single-Point AF where you select the AF point, or Auto-Area AF, where the camera selects the AF point(s) for you.  I suggest you nearly always select your own desired AF point.

Continuous-Servo AF (AF-C)
Use this mode when your subject is moving.  If the subject is moving towards you or away from you, the camera will keep evaluating the focus distance, as long as the Shutter Button is kept half-pressed.  You will need to use this in conjunction with the Autofocus Area Modes to determine if and how the camera tracks the subject laterally to the surrounding AF points, or if it will only track the subject if it remains at the initially selected AF point.  If the subject is going to be difficult to follow or is moving across your field of view, set the AF-Area Mode to one of the Dynamic-Area AF modes or to the 3D-Tracking mode.  Focus on the moving subject with the selected point if using Single-Point, one of the Dynamic Area Modes, or 3D-Tracking, or let the camera select the AF point in Auto-Area AF, and then as long as the Shutter Button remains half-pressed the camera will track the subject as it moves closer or farther in distance.  Depending which AF Area Mode you are using, the camera may also maintain focus or track the subject to some or all of the surrounding focus points if it moves away from the initially selected point.  More about this in the Autofocus Area Modes section just below.

Auto-Servo AF (AF-A)
This mode is a hybrid of the two other focus modes.  It starts in Single-Servo AF (AF-S) mode then changes to Continuous-Servo AF (AF-C) mode if your subject starts moving.  Why shouldn’t you use this all the time, then?  Well, if you are focusing and then recomposing, as you may often be doing, your movement of the camera may fool it into thinking that the subject is moving and your resulting focus may not be where you want it to be, or may not be as accurate as it might be if you are using Single-Servo AF.

The arrangement and position of the 39 AF points of the Nikon D600, shown with the optional viewfinder grid display.

Manual Focus
Sometimes you may be taking several photos of the same subject from the same distance, or for some other reason want to keep the same focus distance and not have to keep re-focusing and re-composing.  Or you may be taking multiple photos for a panorama.  In these situations, turn off the auto-focus on your lens by switching from AF to M with the camera’s Focus Mode Selector switch and with the A/M switch on the lens itself.  Just remember to switch them back when you are finished.  You may also wish to do this if you want to precisely manually focus with the focus ring on your lens.  For lenses with “full time manual focus” however, you don’t need to switch to M in order to manually override the autofocus with the lens focus ring.  These lenses will have M/A and M on the lens focus mode switch instead of A and M.

Autofocus Area Modes
The Autofocus Area Modes are used to set if just a single AF point is active or else how many AF points surrounding your selected AF point will be used to maintain focus or to track a moving subject if you are using AF-C or AF-A Autofocus Modes.

Single-Point AF
Only one AF point will be active, and surrounding AF points will not become active to maintain focus or to track a subject that moves away from the one selected point.  This is typically used along with Single-Servo AF (AF-S) to focus on a stationary or still subject, or in a situation where you will be reframing the shot after you lock focus at a specific distance.  It can also be used with accuracy with AF-S mode for moving subjects if you take the photo quickly or if you recompose and take the shot quickly after locking in focus, especially if the camera-to-subject distance does not change at all or very much in that period between locking focus and taking the photo.  Use the Multi Selector to choose your active AF point as you look through the viewfinder and use the OK Button to quickly select the center AF point.  Also, remember that Custom Setting a6 allowed you to choose between having all 39 AF points available or to limit the camera to 11 AF points.  If you are just starting out with manually selecting a single Focus Point, you may wish to limit them to 11 now, and when you get the hang of it or when you are using one of the other AF Area Modes described below, increase it to 39 to take full advantage of all the AF points of the D7000 autofocus system.  If you choose Single-Point AF with Continuous-Servo AF (AF-C) or Auto-Servo AF (AF-A) for tracking moving subjects, it will only track the subject as long as it is positioned at the selected AF point, and it will not be tracked laterally to the other, surrounding points.  In other words, the single AF point you select will track a subject if it moves closer or farther away, but the AF system will not follow or track the subject if it moves left, right, up, or down and away from your selected AF point.  To do this, you use Dynamic-Area AF Mode or 3D-Tracking.

Dynamic-Area AF
With the Dynamic-Area AF Modes, you select an AF point to tell the camera where to autofocus, and if your subject briefly moves away from that point to a neighboring point or if you lose the subject from your AF point while panning, the camera will use the surrounding AF points to help maintain focus on it.  Select one of the Dynamic-Area AF options (below) when you are photographing moving or potentially moving subjects using Continuous-Servo AF (AF-C) or Auto-Servo AF (AF-A).  These modes are ideal for a subject moving closer or further from the camera but which may also move laterally away from the selected AF point faster than you can react in order to keep it located at that point, or for when you are panning and following the subject and attempting to keep it located at the selected AF point, but may have a little or a lot of difficulty doing so.  Remember that you need to keep the Shutter Button half-pressed in order for the continuous focusing at the initial point or the surrounding points to occur.  Note that the camera may pick up and start tracking a new subject that falls under the selected AF point if you lose your initial subject, in part determined by your setting for Custom Setting a3.

9-Point Dynamic-Area AF will use the immediate surrounding AF points to help maintain focus on a subject that briefly leaves the selected AF point.  This can be used with predictably moving subjects, like a runner or vehicle moving towards you or one that you can easily follow laterally by panning.

21-Point Dynamic-Area AF will use even more of the surrounding AF Points, more than half the total AF Points, to help maintain focus on a subject that briefly leaves the selected AF point.  This should be used for more unpredictably moving objects, like sports players on a field, which may quickly move further away from your selected AF point before you have a chance to realign that point over the subject.

39-Point Dynamic-Area AF (or 51-Point Dynamic-Area AF with the D7100) will use all of the 39 AF points (or 51 points) to help maintain focus on a subject that briefly leaves the selected AF point.  It can be used for very quick and unpredictably moving subjects, like pets, birds or other wildlife, and all 39 AF points will be used to maintain focus on the subject as you attempt to realign the selected AF point with the subject.

The Dynamic-Area AF Modes are not used to track and maintain focus on a subject that is moving across the various AF points in the frame, but rather are used to stay focused on a moving subject that you attempt to keep located at your selected AF Point.  To track a subject that is moving across the frame, intentionally passing from one AF point to the next, use 3D-Tracking.

A simulated image of the Nikon D5200 viewfinder, showing the autofocus focus points active with 9-Point Dynamic Area AF area mode, when the center AF point is selected. (Image shown at 50% opacity to better view AF points.)

This mode is used for subjects moving across the frame in any direction, or subjects moving erratically from side-to-side in the frame, and they are tracked by areas of color.  This is used when you don’t wish to necessarily pan or follow the subject to keep it located in the same part of the frame, but rather when you wish to keep the camera relatively still as the subject moves across the frame.  You may select this option when you are tracking and photographing moving subjects using Continuous-Servo AF (AF-C) or Auto-Servo AF (AF-A).  Again, you choose the initial AF point to locate the subject and begin the tracking.  If the area of color you wish to track is too small or if it blends into the background, this mode might not be very effective.

Auto-Area AF
The camera uses all 39 AF points to detect what it thinks is the subject and automatically choose the appropriate AF point(s).  Typically, the camera will select the nearest subject or a human in the frame, so it may not focus on exactly what you wish to focus on.  That is why it is best to use one of the other modes and select the AF point yourself.

Group Area AF
The Nikon D810 and D4s include the Group Area AF autofocus area mode, which makes use of a group of 5 AF Points arranged in a cross-shaped pattern. And instead of selecting a primary point with the surrounding points being “helper points,” you will actually be selecting the group of five points, which will all be used to attempt to focus on the subject. Unlike the other AF Area Modes with multiple points, the Viewfinder will actually display the four outer points of the group, but for some reason not the central point – perhaps so that you can better view the subject.

Keep in mind that with the other somewhat similar Dynamic Area AF modes, you choose a primary point and attempt to keep the subject located at that point, and the surrounding points act as “helper” points if the subject happens to move away from the primary point. But with Group Area AF you select the entire group of AF Points, and they all work equally to focus on the subject. This mode can be used similar to Single Point AF but when it might be challenging to locate the subject under an individual point. When working in AF-S Focus Mode and using Group Area AF, the selected AF points will give priority to faces if they are present, otherwise they will focus on the closest subject.


The next step is to learn to lock focus independent of locking exposure, and customize the camera’s controls to perform these functions how you wish.  But you are going to have to have a look at my e-book guides Nikon D7100 Experience, Nikon D7000 Experience, Nikon D600 Experience and Nikon D5200 Experience to learn about this and many other important functions of your sophisticated Nikon D600, D5200, or D7000!

To learn about another important reason why you need to take control of your autofocus system, see the related post:

Don’t Let the Locations of the AF Points Dictate Your Composition

What do you do when, with your desired framing, your subject is not located exactly under or near an AF point? Even with all the AF points of an advanced Nikon D7000 and D600, this will often be an issue. Have a look at the above post to learn why this is an issue and how to resolve it.
