• Auto-area AF: The camera automatically
detects the subject and selects the focus
point; if a face is detected, the camera will
give priority to the portrait subject. The
active focus points are highlighted briefly
after the camera focuses; in AF-C mode, the
main focus point remains highlighted after
the other focus points have turned off.
AF-area mode can be
selected by pressing the
AF-mode button and
rotating the sub-
command dial until the
desired setting is
displayed in the
viewfinder and control
panel.
A
3D-tracking
When the shutter-release button is pressed halfway, the colors in the
area surrounding the focus point are stored in the camera.
Consequently 3D-tracking may not produce the desired results with
subjects that are the same color as the background or that occupy a
very small area of the frame.
