How to adjust 51 focus points on Nikon d7100

Operation steps:

1. Press and hold the focus mode button (the top of the lever) and then turn the front wheel.

2. The camera will switch between several focus modes.

3. When selecting 51-point focus, all focus points will light up as shown.

4. However, in actual shooting, most of the time only a few match up.

1. Steps to select the number of focus points:

1. Press the MENU menu key and press the up and down arrows to select the reset custom menu;

2. Select the a6 option in the custom settings menu, select AF51, and press OK to set.

2. Like the D7100, there are 51 focus points to choose from, which is quite a lot. The camera will usually automatically select according to a predetermined program, or it can be selected manually.

3. If the entire viewing range is covered by focus points, it will increase the difficulty of manufacturing the camera hardware and greatly increase the cost. At the same time, the composition of the subject around the edges of the frame is very important in photography practice. It rarely happens, and even if it does, it can be taken well with a little control, so there is no camera that covers the entire viewing range.
