Reference-Focus Focus 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 S locks when in-focus indicator (●) appears in viewfinder, and remains locked Single- while shutter-release button is pressed halfway (focus lock). At default set- servo AF tings, shutter can only be released when in-focus indicator is displayed (fo- cus priority). C Continuous- servo AF Camera focuses continuously while shutter-release button is pressed halfway. If subject moves, focus will be adjusted to compensate (predictive focus tracking; 52). At default settings, photographs can be taken whether or not camera is in focus (release priority). Camera does not focus automatically; focus must be adjusted manually us- M Manual ing 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 when photographing stationary subjects. Continuousservo AF may be a better choice with erratically-moving subjects. Manual focus is recommended when the camera is unable to focus using autofocus. 51
