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 S Camera focuses when shutter-release button is pressed halfway. Focus Single-servo locks when in-focus indicator (●) appears in viewfinder, and remains AF locked while shutter-release button is pressed halfway (focus lock). Camera focuses continuously while shutter-release button is pressed C halfway. If subject moves, camera will engage predictive focus track- Continuous- ing to predict final distance to subject and adjust focus as necessary. servo AF At default settings, shutter can be released whether or not subject 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. Choose single-servo AF for landscapes and other stationary subjects. 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. 74
