[ 3D-tracking ]
The user selects the focus point; while the shutter-
release button is pressed halfway, the camera will track
subjects that leave the selected focus point and select
new focus points as required. This option is available

to side (e.g., tennis players).

The camera focuses using a group of focus points
selected by the user. Priority is given to faces detected
by the camera, if any.
• Choose for snapshots, subjects that are in motion,
and other subjects that are difficult to photograph
using [

[ 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.
