AUTOFOCUS (AF) MODES

In this section you will learn how to set the Auto Focus (AF) mode for the Nikon cameras. This lesson will show you how to set the mode for the D5100 and D5200 models. Should you have a different model please see your teacher to find out how to set the point for your camera.

The auto focus mode differs from the point as you will now tell the camera how you want to focus instead of where. Your options are to focus continuously, just once, or auto focus.
