One of the most important features on the D7200 is its improved AF system. Nikon has updated the D7200 to its Multi-CAM 3500DX II system, which still offers 51 AF points (the central 15 of which are cross-type), but now all of those points are sensitive to -3EV, while the D7100’s were limited to -2EV.
The most obvious improvement in the D7200 compared to the D7100 will be noticed by anyone who shoots continuously. The buffer size on the D7100 was tiny and filled up almost instantly, which not only affected burst shooting but bracketing as well. You can now fire away with the D7200 for up to 18 14-bit lossless compressed, 27 12-bit compressed Raws, or 100+ JPEGs. The maximum burst rate remains the same: 6 fps at full size and 7 fps in 1.3x crop mode.
The D7200 can now extend its ISO higher than on its predecessor, but with a catch. Seeing how little color detail would be left at ISO 51,200 and 102,400, Nikon has chosen to make those two sensitivities black and white only.
Two other new features of note are 60p video (with Flat Picture Control, also available for stills) and Wi-Fi. While the addition of 60p video is nice, it’s only available in 1.3x crop mode. The D7200 also has Wi-Fi with NFC, which Nikon has branded ‘SnapBridge’, which allows for remote camera control and image transfer.
