This section describes the options that control how your camera
focuses when photographs are framed in the viewfinder. Focus
can be adjusted automatically (see below) or manually (
0 101).
The user can also select the focus point for automatic or manual
focus (
0 96) or use focus lock to focus to recompose photographs
after focusing ( 0 98).
To use autofocus, rotate the focus-mode
selector to AF.

Choose from the following autofocus modes:

Mode Description
AF-S
Single-servo AF : For stationary subjects. Focus locks when shutter-
release button is pressed halfway. At default settings, shutter can
only be released when in-focus indicator (
I) is displayed (focus
priority; 0 282).
AF-C
Continuous-servo AF : For moving subjects. Camera focuses
continuously while shutter-release button is pressed halfway; if
subject moves, camera will engage predictive focus tracking (

to predict final distance to subject and adjust focus as necessary.
At default settings, shutter can be released whether or not subject
is in focus (release priority;
0 281).
