The combination of focus areas in Group Dynamic AF Mode can be changed as
follows in Custom Setting “a3: Group dynamic AF” (x 94):
Focus area pattern can be changed among six focus area groups—center 1,
center 2, top, bottom, left and right (Pattern 2 Closest, Pattern 2 Center).
In Pattern 1 Closest and Pattern 2 Closest, Dynamic AF with Closest-Subject
Priority can be performed with focus areas within a group.
Center 1 Top Bottom Left Right
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.
Pattern 1 Center (default)
Press the center of the multi-selector to switch between Center 1 and Center
2. However, if “Center AF area” is not selected in Custom Setting “f1: Center
button” (x 107), Center 1 and Center 2 cannot be switched.
