Rotate AF Area mode selector to select AF Area mode. • Set focus mode selector to S (Single Servo AF with Focus-Priority) or C (Continuous Servo AF with Release-Priority). Camera focuses automatically on the subject when the shutter release button is lightly pressed. S: Single Servo AF with Focus-Priority The shutter can only be released when in focus indicator / appears in the viewfinder (Focus-Priority). Once focused on a subject, keeping the shutter release button lightly pressed locks focus (Focus Lock, page 44). With a subject that has been moving, the camera continuously focuses on a subject as long as the shutter release button is kept lightly pressed (Focus Tracking, page 88) and focus locks when the subject stops moving. C: Continuous Servo AF with Release-Priority Since the priority is on shutter release, you can release the shutter regardless of the focus status (Release-Priority). Focus is not locked when / appears in the viewfinder and the camera continues to focus on a subject until shutter release. With a moving subject, the camera continuously focuses on a subject as long as the shutter release button is kept lightly pressed (Focus Tracking, page 88). c 11: Autofocus detection can be set to start by pressing the AE-L/AF-L button only (not by lightly pressing the shutter release button) (page 73).

This mode is useful for achieving accurate focus on a selected focus brackets when shooting a stationary subject. ©: Dynamic AF j/J (in Dynamic AF Mode with Closest Subject Priority) In Dynamic AF, you designate the primary sensor (the first to detect the subject), then if the detected subject moves, Dynamic AF automatically shifts to the next sensor that detects the subject, then the next again, shifting among the progression of sensors as the subject moves. Dynamic AF thereby follows and maintains accurate focus even on subjects that move irregularly. (LCD panel and viewfinder indications do not change as sensoring shifts in Dynamic AF mode.) Dynamic AF Mode with Closest Subject Priority can also be activated in Dynamic AF mode. See next page. If the focus mode is set to Single Servo AF in Dynamic AF, the camera is automatically set to Dynamic AF Mode with Closest Subject Priority in initial setting. Focus 38 39
