To learn more about about the Nikon D5100 autofocus system as well as how to fully take control of your camera in order to consistently capture better images, please have a look at my e-book user’s guide Nikon D5100 Experience. It not only explains all the features and controls but also when and why to use them in real life photography.
In addition to delivering great image quality, exceptional low light/high ISO performance, and rugged construction, the Nikon D7000 is an extremely sophisticated camera that can be highly customized to work exactly how you want or need it to. Its autofocus system and metering system can be set up and tweaked according to your preferences, its buttons and dials can be assigned and customized for your most-used functions, its frame rates can be adjusted, its white balance fine-tuned, and much more. I’ve spent a lot of time with the Nikon D7000 as I researched and wrote my e-book user’s guide to the D7000 called Nikon D7000 Experience, and here are the some of the top “tips and tricks” I’ve discovered for setting up and using this powerful dSLR (in no particular order):
1. Take Control of your Autofocus System: In order to always ensure that the camera autofocuses where and how you want, you need to take control of your AF system. Use AF-S Autofocus Mode and Single Point AF Autofocus Area Mode for still subjects, and use AF-C Autofocus Mode and Dynamic Area AF or 3D-Tracking Autofocus Area Mode for tracking moving subjects. Select your desired AF point so that the camera focuses on, or begins to track, your intended subject. Press the AF Mode Button and then turn the Command and Sub-Command Dials to change the Autofocus Mode and Autofocus Area Mode as you view the settings on the top LCD screen. There is so much more you can do with the AF system, including selecting the number of active AF points and determining exactly how it tracks moving subjects. I wrote an entire previous post that goes into more detail about the settings and capabilities of the D7000 autofocus system.
2. Set up your Dual SD Memory Card Slots: The two memory card slots of the D7000 can function in a couple different ways, including using one for RAW 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 stills 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.
3. Set or Create a Picture Control for your JPEG Images and Movies: If you are shooting in RAW (NEF) or JPEG and will be post-processing your images in Photoshop, Lightroom, or using the Nikon software, then you don’t need to worry about Picture Controls. If that is the case, set the Picture Control for Standard or Neutral and that way 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. 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 Control that best creates your desired look. Adjust the contrast, saturation, brightness, and sharpening to achieve the look you are after. Save the Picture Controls 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 styles to be found online that recreate the look of various roll films including Kodachrome and Velvia.
4. Verify that you Haven’t Over-Exposed Your Highlights: View your histogram along with your image during image review or image playback to confirm that you haven’t over- or under-exposed your image. To see the Overview image-view that shows the histogram, press up or down on the Multi-controller during image playback to flip through the different available views. The histogram will show you if your highlights or shadows have run off the graph, indicating that those areas of the image contain no detail in the highlights or shadows other than pure white or pure black. In the RGB Histogram and Highlights view, the over-exposed highlights will also blink in the tiny image, indicating that those areas of the image have been “blown-out” and that there is no detail other than pure white in those parts of the image. If you have over- or under-exposed your image, then…
5. Make use of Exposure Compensation: Explore the various options in Custom Setting b3 to customize exactly how exposure compensation works. 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 f6. 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 use to set EC. This last option is the most sophisticated and most flexible, and may be the best one to learn and use. 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. EC 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 D7000, right? So that you can take advantage of these sophisticated controls!
Brief Commercial Interruption: Are you already getting a little confused? Want to learn more about these and other features of the D7000? I recently completed an e-book user’s guide for the Nikon D7000 called Nikon D7000 Experience that explains all of this and much more. The guide covers all the Menus, Custom Settings, functions and controls of the Nikon D7000, focusing modes, exposure modes, shooting modes, white balance, etc., PLUS when and why you may want to use them when shooting. As one reader has said, “This book, together with the manual, is all you need to start discovering all the camera’s potential.” It will help you to take control of your camera and the images you create! Learn more about the features and settings discussed in the ” tips and tricks” here and much more. To read more about the book, preview it, and purchase it, see my Full Stop bookstore website here!

6. Fine-Tune the Exposure Metering Modes: Using Custom Setting b5, you can fine-tune the exposure for each of the different Exposure Metering Modes (Matrix, Center-Weighted Average, Spot), all independently. For example, if you find that Center-Weighted metering is slightly under-exposing all the time, fine-tune it for +1/3 or +2/3 using Custom Setting b5. This tweaks the exposure behind the scenes, independent of exposure compensation. You can still continue to use EC as always, on top of this fine-tuning.
7. Lock Exposure and Focus Independently: Sometimes you need to lock the focus distance before recomposing, or lock the metered exposure setting for one shot or for several shots in a row. Or sometimes you need to lock both focus and exposure for the same shot, perhaps independently of each other. By default, the Shutter Button locks focus when you half-press it and exposure is determined when you fully press the Shutter Button to take the shot. You can use Custom Setting c1 to have the Shutter Button half-press also lock exposure, or better yet use Custom Setting f3 to use the Fn Button for locking exposure. You can even set it so that you either press and hold the Fn Button or just press it and release. Then you can use Custom Setting f5 to set the AE-L/AF-L Button for locking focus. This is known as back-button focusing and that way you can lock these settings independently. Learning to use back-button focus and even exposure lock can be awkward at first, and you may not fully understand why it is necessary. But I highly recommend starting to experiment with them, then hopefully getting in the habit of using them all the time – especially if you shoot a lot of action scenes or situations where you are rapidly taking lots of photos (perhaps a wedding and reception), or if you are recomposing your framing between when you focus and when you take the shot. You may soon find them both indispensable and wonder how you once managed without them!

8. Reverse the Values of the Exposure Indicators: In the viewfinder and on the top LCD screen of the Nikon D7000, the exposure indicator shows the negative values on the right and the positive values on the left. Perhaps you find this as counter-intuitive as I do. Ever since grade school, negative values have always been to the left! Plus with the histogram, the brighter values are shown on the right of the graph, and thus to make use of exposure compensation you would dial to the negative side to correct for over-exposed values, thus moving your histogram to the left. So why do you have to move the value to the right on the exposure indicator? It can obviously cause great confusion! Use Custom Setting f9 to reverse the indicators to the more logical orientation.
9. Put Your Most Used Settings in My Menu: Instead of digging 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. Determine what settings you are digging into the menus to look for and change most often, and put them in My Menu, such as maybe Format and White Balance (for more WB options and fine-tuning). I recommend you include Format since you should re-format your memory card each time you are ready to clear off that card, and not just Erase All. However, put Format lower down in My Menu so that you don’t have a tragic memory card accident.
10. Make Use of the Other Exposure Modes: While Matrix Metering will do an excellent job of determining the proper exposure of an image 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. It is best to turn to one of these other modes to ensure you properly meter for the subject and don’t blow the shot. If the background is not dramatically lighter or darker than the subject, but you still want to ensure that the camera’s metering system concentrates on the subject and not the entire scene, use Center-Weighted. This is a situation where you may wish to lock in the exposure and recompose if your subject is not going to be in the center in the final framing. You can even use Custom Setting b4 to change the size of the area being metered with Center-Weighted metering. If the background is very dark or light and you want the camera to ignore it and just meter on a certain critical area of the scene, use Spot metering. Again, meter for that critical area, lock the exposure, and recompose.
10a. Quickly Use Spot Metering to Determine a Critical Exposure: You can use Custom Setting f4 to assign the Depth-of-Field Preview Button to Spot Metering so that you can quickly meter for a precise area without having to take your eye from the viewfinder and change the Metering Mode. Versatile Custom Settings such as this are a big part of what makes the D7000 such a powerful, customizable camera, and this demonstrates why it is worthwhile to completely understand and take advantage of these advances capabilities.
There are many more great features and settings of the Nikon D7000 to take advantage of. You have a powerful camera in your hands, so why not learn to take advantage of its advanced features?! Have a look at my e-book guide Nikon D7000 Experience to learn more about the settings, features, and controls mentioned here, and so much more. Learn to take control of your camera and the images you create!
Also, please know that there aren’t really any tips or tricks for better photography. To improve your photography, simply learn your camera inside and out and learn the techniques of dSLR photography (with my e-book!) and then practice, practice, practice taking images, study the results, and look at and learn from the work of talented photographers.
Have a look at that post I mentioned earlier about the autofocus system of the D7000, and another post I’ve written which discusses the Menus and Custom Settings of the D7000. Some of the same items are addressed, but there is also much additional information to be found in the older posts.

The autofocus system of the Nikon D5100 may not be quite as complicated as the 39 point AF system of the Nikon D7000, but it does offer many of the same capabilities and options, and can be a little confusing to figure out. The autofocus system includes not only the three Focus Modes used in various combinations with four Autofocus Area Modes, but also includes a few Custom Settings as well as the optional AF-L or Autofocus Lock Button.
Image by author – copyright 2011 – please do not use without permission!
You will first want to set up the autofocus Custom Settings so that the AF system functions how you desire.
a1: AF-C priority selection – This setting determines if attaining focus is top priority when you are in Continuous-servo AF mode (AF-C autofocus mode), 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.
a2: Built-in AF-assist illuminator – This is used to enable or disable the autofocus assist light, to assist you in autofocusing in low light. Note that the AF-assist lamp only works in AF-S mode or when the camera is in AF-A and choosing single-servo (not always under your control), and when in Auto-area AF area mode or only with the center AF point in other AF area modes.
a3: Rangefinder – This setting is used to help obtain focus when you have turned off autofocus and are using Manual Focus mode (MF) and manually focusing. (Be sure to also set the autofocus switch on your lens to M) The exposure indicator in the viewfinder is used to indicate if the subject is correctly in focus.
f2: Assign AE-L/AF-L button – This is to assign the function of the AE-L/AF-L Button., which gives you the option to use this button to lock focus or to initiate focus, and this separate those functions from the Shutter Button.
This should get you started, and I go into more detail about each of these Custom Settings, as well as all the other D5100 Custom Settings in my e-book guide Nikon D5100 Experience.
Using Autofocus
The information below is also excerpted from my e-book user’s guide Nikon D5100 Experience, so I hope you have a look at the guide in order to learn more about the AF system as well as all the other functions and controls of the D5100.
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 human subject. 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 and selecting a specific AF point. This does not mean you have to manually focus the camera, it means you tell the camera exactly where to autofocus. But you also need to select the desired Focus Mode and Autofocus Area Mode, based on your subject and its type of movement (or lack of movement).
Focus Modes
The D5100 has three different Focus Modes to choose from, typically depending if your subject is still or moving. It also has 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 Focus 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 so that the camera focuses exactly where you want it to.
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-Release 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. Single-Point AF will only track the subject’s distance as it moves near or far if it remains under the selected point. It will not track lateral movement if the subject leaves the selected AF point. If the subject is going to be moving somewhat unpredictably and may leave your selected AF point before you can react, use the Dynamic-Area AF mode so that the surrounding AF points are used to maintain focus while you realign your selected AF point with the subject. If the subject is going to be moving across your field of view, set the AF-Area Mode to the 3D-Tracking mode so that the camera tracks it in any direction as it moves to the other AF points.
Focus on the moving subject with the selected AF point when using Dynamic Area Mode or 3D-Tracking Mode, or let the camera select the AF point in Auto-Area AF Mode, and then as long as the Shutter-Release Button remains half-pressed the camera will track the subject to the other focus points if it moves to them and as it moves closer or farther in distance.
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.
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 with the autofocus switch on the lens itself (set to M) and change your camera’s Focus Mode to MF (Manual Focus). 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. (Note that for lenses with “full time manual focus” you don’t need to switch to M in order to manually override when slightly tweaking 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.) Use the Rangefinder feature of the D5100 to assist with manual focus – Custom Setting a3.
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 track a moving subject if you are using AF-C or AF-A Focus Modes.
Selecting an AF Point using Single-Point AF and locking focus
Single-Point AF Only one AF point will be active, and surrounding AF points will not become active 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. 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. As noted above, the single AF point you select will track a subject if it moves closer or farther away, but the AF system will not 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 mode.
Dynamic-Area AF With the Dynamic-Area AF Mode, 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 Dynamic-Area AF 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.
The Dynamic-Area AF Mode is not used to track and maintain focus on a subject that is moving across the various AF points in the frame, but rather is 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.
3D-Tracking 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 11 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. However in certain situations such as quick sports or action scenes you may have to make use of this.
Locking Focus
The next step is to learn to lock focus independent of locking exposure, typically through the use of the AE-L/AF-L Button as noted in the f2 Custom Setting above. But for that, and numerous other important functions of the D5100, you are going to have to have a look at my e-book, Nikon D5100 Experience!
I’ve put together a video introduction to the D5100 autofocus system to compliment this article:
To learn about another important reason why you need to take control of your autofocus system, see the related post:
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 D5100 or D7000, 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.
