Single-point vs. multi-point autofocus

With a single focus point, you choose a specific area for the camera to focus on. It is useful for still subjects and situations where the camera might otherwise choose the wrong object.

Larger areas help with movement

Zone, wide-area and automatic selection modes give the camera more room to follow a moving subject. They can be faster to use, but the camera has more influence over which detail is prioritised.

Focus area and focus mode are different

AF-S or AF-C controls whether focus locks or continues updating. Single point, zone or wide area controls where the camera looks. You often choose one setting from each group.
