Focus

This section describes the focus options available when photographs are framed in
the viewfinder. Focus can be adjusted automatically (see below) or manually
(0 103). The user can also select the focus point for automatic or manual focus
(0 101) or use focus lock to focus to recompose photographs after focusing (0 102).

Autofocus

To use autofocus, rotate the focus-mode selector to AF.

Autofocus Mode

Choose from the following autofocus modes:
Mode
Auto-servo AF: Camera automatically selects single-servo autofocus if subject is stationary,
AF-A
continuous-servo autofocus if subject is moving.
Single-servo AF: For stationary subjects. Focus locks when shutter-release button is pressed
AF-S halfway. At default settings, shutter can only be released when in-focus indicator is
displayed (focus priority; 0 221).
Continuous-servo AF: For moving subjects. Camera focuses continuously while shutter-
release button is pressed halfway; if subject moves, camera will engage predictive focus
AF-C tracking (0 100) 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; 0 221).
A
Predictive Focus Tracking
In AF-C mode or when continuous-servo autofocus is selected in AF-A mode, the camera will
initiate predictive focus tracking if the subject moves toward or away from the camera while
the shutter-release button is pressed halfway. This allows the camera to track focus while
attempting to predict where the subject will be when the shutter is released.
