Choosing a Focus Mode

When you are using Program, Aperture-priority, Shutter-priority, or Manual
exposure mode, you can select the Autofocus mode when the D7200 measures
and locks in focus prior to pressing the shutter release down all the way and
taking the picture. To specify when the D7200 locks in focus, follow these
steps:
1. Activate autofocus. Make sure the camera is set for autofocus mode by
sliding any MA/M or AF/M switch on the lens to the MA or AF position.
The camera body AF/M switch (see Figure 1.10) must also be set in the
AF position. Note that the autofocus/manual focus switches on the lens
and camera body must agree; if either is set to manual focus, then the
D7200 defaults to manual focus regardless of how the other switch is set.
Nikon, in fact, specifically warns against using autofocus lenses with the
lens switch set to M and the camera body switch to AF, saying that doing
so could damage the camera.
2. Enter setting mode. Press and hold the autofocus mode button in the
center of the AF/M switch.
