: 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.
