Nikon D780 DSLR Camera (Body Only) - Manual (Page 192)

146 Shooting Settings
[ 3D-tracking ]
Select the focus point. While the shutter-release
button is pressed halfway in
AF-A and AF-C focus
modes, the camera will use all 51 focus points to track
subjects that leave the selected point and choose new
points as required.
• Use to quickly compose pictures with subjects that
are moving erratically from side to side (e.g., tennis
players).
• If the subject leaves viewfinder, remove your finger
from the shutter-release button and recompose the
photograph with the subject in the selected focus
point.
[ Group-area
AF ]
The camera focuses using a group of focus points
selected by the user, reducing the risk of the camera
focusing on the background instead of on the main
subject.
• Use for snapshots or photos of moving subjects that
are hard to frame using the [
Single-point AF ] option.
• Face detection is enabled. The camera gives priority
to any faces detected.
