3D-Tracking
If subject leaves the viewfinder, remove your finger from the shutter-release button and
recompose the photograph with the subject in the selected focus point. Note that 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.
