Notes About AF Area Mode
When digital zoom is in effect, focus will be on the center of the screen regardless
of the AF area mode setting.
The setting may not be changed when using certain settings of other functions.
The camera focuses on the subject in the center of the
frame.
When the camera detects the main subject, it focuses on
that subject.
See "Using Target Finding AF" (A60) for more
information.
