The D7200 is a very minor upgrade over the D7100, but it does offer one important improvement: a larger buffer. While the D7100’s buffer filled up after about six shots (of 14-bit uncompressed raw photos), the D7200 can take 17 shots. That means you can hold the shutter down longer during sports and wildlife shooting, and you might be able to use raw instead of just JPG when shooting action. The D7200 is the best Nikon camera for action photography where you can’t fill the frame using a full-frame camera. In other words, if you plan to use a 70-200 lens but you can’t get close enough to the action and you need to crop anyway, you’ll get sharper results with the D7200 than you will with any other camera in the Nikon lineup, including the D810. However, as a sports camera, the D7200 pales in comparison to the Canon 7D Mark II. The Canon takes ten pictures in a second, whereas the Nikon captures only six. That difference is huge to a sports or wildlife photographer—it increases the odds that you’ll capture a shot the exact moment the athlete kicks the ball, or that you’ll have perfect timing as a flying bird’s wings hit their apex. The Nikon does have slightly better image quality than the D7200, but owning both, I always choose the 7D Mark II for sports and wildlife.
