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 out-
of-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
