Focus-mode selector

Focus Mode

Focus mode is controlled by the

focus-mode selector on the front of the camera. There are two autofocus (AF) modes, in which the camera focuses automatically

when the shutter-release button is

pressed halfway, and one manual focus mode, in which focus must N be adjusted manually using the focusing ring on the lens:

Choose single-servo AF for landscapes and other stationary sub- jects. Continuous-servo AF may be a better choice with erratically- moving subjects. Manual focus is recommended when the camera is unable to focus using autofocus.
