Modern cameras use a system of focusing points distributed across the frame for automatic focusing, known as autofocus. The user can choose which of these points the camera uses. AF Point Groups are one of the options for this selection. Instead of activating a single focusing point, a small, predefined zone composed of several nearby points is selected. The camera then focuses on the nearest object located within this active group. This setting is a compromise between the precision of a single point and fully automatic selection from the entire sensor area. It is particularly useful when photographing moving subjects, where it is difficult to keep a single focusing point precisely on the target, such as in sports or wildlife photography.
