j:Dynamic AF Mode with Closest-Subject Priority

Dynamic AF Mode with Closest-Subject Priority automatically selects the focus area nearest to the closest subject. Focus is constantly maintained within one of the 11 focus areas so pictures are always in focus.

In Single Servo AF with Focus-Priority, the area of the subject in focus is highlighted momentarily in the viewfinder. If “Focus priority” is selected in

Custom Setting “a1: AF-C priority” (x 94), the area of the subject in focus is also highlighted even in Release-Priority,.

All focus areas are highlighted with “ ” in the rear LCD panel (in normal and detailed displays).

Focus may not be achieved on the closest subject when a telephoto lens is used or when the subject is too dark. In these situations, use Single Area AF Mode.
