I’ve put together a comprehensive Nikon D850 Menu Setup Spreadsheet, with suggested settings for various types of shooting situations, such as Landscape, Action/Sports, Portrait, Concert, etc. The Excel spreadsheet covers all of the Photo Shooting Menu items, all of the Custom Settings, and various other camera and exposure settings. A free link to the spreadsheet is included inside my Nikon D850 Experience guide if you purchase that, otherwise you can purchase and download the spreadsheet here, where you will also find instructions for printing it out:
Here is an image of just a small portion of the comprehensive spreadsheet:
The setup guide spreadsheet is a great companion to my full D850 guide, Nikon D850 Experience, which is a clear and comprehensive guide to the camera. The full guide explains all the Menu and Custom Settings items, as well as all of the other camera features, functions, and controls.
