a: Autofocus
a1: AF-area Mode
This option (available in all shooting modes) determines how the focus point for
autofocus is selected.
Choose from the following options:
The current setting is shown in the shooting information display
(pg. 10).
A
3D-tracking (11 Points)
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.
Option Description
K Single point
User selects focus point using multi selector; camera focuses on subject in
selected focus point only.
Use with stationary subjects.
Default setting
for n mode.
I
Dynamic
area
In AF-A and AF-C autofocus modes, user selects focus point manually, but
camera will focus based on information from surrounding focus points if
subject briefly leaves selected point.
Use with erratically moving
subjects.
In AF-S autofocus mode, user selects focus point manually; camera
focuses on subject in selected focus point only.
Default for m mode.
H Auto-area
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.
Default for i, j, k, l, o, P, S, A, and M
modes.
f
3D-tracking
(11 points)
In AF-A and AF-C autofocus modes, user selects focus point using multi selector.
If user changes composition after focusing, camera uses 3D-tracking to
select new focus point and keep focus locked on original subject while
shutter-release button is pressed halfway.
Use to recompose
photographs while shooting relatively static subjects.
If subject leaves
viewfinder, remove your finger from shutter-release button and
recompose photograph with subject in selected focus point.
In AF-S
autofocus mode, user selects focus point manually; camera focuses on
subject in selected focus point only.
