•
If [Face and eye detection on] is
selected and a portrait subject is
detected, an amber border indicating
the focus point will appear around the
subject's face. If the camera detects the
subject's eyes during live view
photography, the border will instead be displayed around one
or the other of their eyes.
•
Faces detected when [Face detection on] is selected are
similarly indicated by an amber border.
•
If AF-S is selected for AF mode, or if AF-A is selected and the
camera is shooting using AF-S, the focus point will turn green
when the camera focuses.
•
If more than one portrait subject or more than one eye is
detected, e and f icons will appear on the focus point, and
you will be able to position the focus point over a different
face or eye by pressing 4 or 2 .
•
If the subject looks away after their face is detected, the focus
point will move to track their motion.
•
During playback, you can zoom in on the face or eye used for
focus by pressing J .
