Choose the focus point.
6 (face-priority AF): A double yellow
border will be displayed when the
camera detects a portrait subject (if
multiple faces, up to a maximum of
35, are detected, the camera will focus
on the closest subject; to choose a
different subject, use the multi
selector). If the camera can no longer
detect the subject (because, for example, the subject has
turned to face away from the camera), the border will no
longer be displayed.
7/8 (wide- and normal-area
AF): Use the multi selector to
move the focus point
anywhere in the frame, or
press J to position the
focus point in the center of
the frame.
9 (subject-tracking AF):
Position the focus point
over your subject and press
J. The focus point will
track the selected subject as
it moves through the frame.
To end focus tracking, press
J a second time.
