WWW.LENSINC.NET AF Area Mode • Autofocus operation lets you select Single Area AF that uses one focus area selected or Dynamic AF that also utilizes the other four focus areas. Rotate AF area mode selector to select AF area mode. • k appears when the Single Area AF is selected and j or J appears when Dynamic AF is selected in the LCD panel. g: Single Area AF With Single Area AF, only the focus brackets selected among five focus areas is used for autofocus. This mode is useful for achieving accurate focus on a selected focus brackets when shooting a relatively stationary subject. ©: Dynamic AF 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. (Viewfinder indication does 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. • Dynamic AF Mode with Closest Subject Priority • The Closest Subject Priority AF operation is possible in the Dynamic AF, where the camera automatically selects the focus area with the closest subject. Focus is always achieved at any of the five focus areas so you can avoid outof-focus pictures. • In Dynamic AF Mode with Closest Subject Priority, focus area indication does not appear in the LCD panel and viewfinder. • When the telephoto lens is attached or the subject is very dark, the closest subject may not be selected. In this case, use Single Area AF. · 9, 10: Dynamic AF Mode with Closest Subject Priority can be set to be cancelled in Single Servo AF in · 9 or activated in Continuous Servo AF in · 10 (page 72). • Autofocus modes Focus mode Focus area I Single Servo AF Selectable Dynamic AF Mode Focus area AF Area mode with Closest LCD panel indication Subject Priority Single Area AF - k Appears II Single Servo AF Automatically Dynamic AF selected Acivated in initial setting j Does not appear III Single Servo AF Selectable Dynamic AF Cancelable with · 9 J Appears IV Continuous Selectable Single Area AF - Servo AF k Appears V Continuous Servo AF Selectable Dynamic AF Not activated in initial setting J Appears VI Continuous Automatically Dynamic AF Servo AF selected Activated with · 10 • See page 86 for the combinations of AF functions. j Does not appear Focus 38 39
