Taking Photographs-Focus Focus Controlling How the Camera Focuses This section describes the options that control how your camera focuses: focus mode, focus-area selection, and AF-area mode. 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 be adjusted manually using the focusing ring on the lens: Option Description Camera focuses when shutter-release button is pressed halfway. Focus locks when in-focus indicator (●) appears in viewfinder, and remains locked while shutter-release button is pressed halfway (focus lock). S Shutter can only be released when in-focus indicator is displayed (fo- Single-servo cus priority). If subject was moving when shutter-release button was AF pressed halfway, camera will track subject until focusing is complete and the shutter can be released (predictive focus tracking; 71). If subject stops moving before shutter is released, in-focus indicator will appear in viewfinder and focus will lock at this distance. Camera focuses continuously while shutter-release button is pressed C halfway. If subject moves, focus will be adjusted to compensate (pre- Continuous- dictive focus tracking; 71). Photographs can be taken whether or servo AF not camera is in focus (release priority). M Manual Camera does not focus automatically; focus must be adjusted manually using the lens focusing ring. If maximum aperture of lens is f/5.6 or faster, viewfinder focus indicator can be used to confirm focus (electronic range finding), but photographs can be taken at any time, whether or not camera is in focus. Choosing single-servo AF ensures a sharp, focused image. 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. 70
