❚❚ Choosing an AF-Area Mode
The following AF-area modes can be selected during live view
photography and movie live view:
Mode Description
!
Face-priority AF : Use for portraits. The camera automatically
detects and focuses on portrait subjects; the selected subject is
indicated by a double yellow border (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.
5
Wide-area AF : Use for hand-held shots of landscapes and other
non-portrait subjects. Use the multi selector to move the focus
point anywhere in the frame, or press the center of the multi
selector to position the focus point in the center of the frame.
6
Normal-area AF : Use for pin-point focus on a selected spot in the
frame. Use the multi selector to move the focus point anywhere
in the frame, or press the center of the multi selector to position
the focus point in the center of the frame. A tripod is
recommended.
&
Subject-tracking AF : Use the multi selector to position the focus
point over your subject and press the center of the multi selector
to start tracking. The focus point will track the selected subject
as it moves through the frame. To end tracking, press the center
of the multi selector again. Note that the camera may be unable
to track subjects if they move quickly, leave the frame or are
obscured by other objects, change visibly in size, color, or
brightness, or are too small, too large, too bright, too dark, or
similar in color or brightness to the background.
