• Auto-area AF: The camera automatically
detects the subject and selects the focus
point. If a type G, E, or D lens is used
(0 320), the camera can distinguish human
subjects from the background for improved
subject detection. 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.

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.
