Af-Area Mode - Nikon D700 User Manual

AF-Area Mode

AF-area mode determines how the
focus point is selected in autofocus
mode. To select the AF-area mode,
rotate the AF-area mode selector.
The following options are available:
Mode
N
K
Single-
point AF
I
Dynamic-
area AF
H
Auto-area
AF
74
User selects focus point manually; camera focuses on
subject in selected focus point only. Use for relatively static
compositions with subjects that will stay in selected focus
point.
• In continuous-servo AF (pg 72), user selects focus point
manually; if subject briefly leaves selected focus point,
camera will focus based on information from surrounding
points. Number of focus points used can be selected from
9, 21, and 51 using Custom Setting a3 (Dynamic AF area,
pg. 285). If 51 points (3D-tracking) is selected for
Custom Setting a3, focus point will be selected
automatically using 3D-tracking.
• In single-servo AF, user selects focus point manually; camera
focuses on subject in selected focus point only.
Camera automatically detects
subject and selects focus point. If
type G or D lens is used (pg. 370),
camera can distinguish human
subjects from background for
improved subject detection. In
single-servo AF, active focus points
are highlighted for about one second after camera focuses.
Active focus points are not displayed in continuous-servo
AF.
