Af-Area Mode - Nikon D3 User Manual

AF-Area Mode

AF-area mode determines how the
focus point is selected in autofocus
mode (pg. 74). To select the AF-
area mode, rotate the AF-area
mode selector. The following
options are available:
N
Mode
K
Single-point
AF
I
Dynamic-
area AF
H
Auto-area AF
76
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. 74), 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. 306). If [51 points (3D-tracking)]
is selected for Custom Setting a3, focus point will be
selected automatically using 3D-tracking.
• In single-servo AF (pg. 74), 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, 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.
