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).

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

Choose from the following autofocus modes:

: Camera automatically selects single-servo autofocus if subject is stationary, 

continuous-servo autofocus if subject is moving.

: For stationary subjects. Focus locks when shutter-release button is pressed 

halfway. At default settings, shutter can only be released when in-focus indicator is 
displayed (focus priority; 

0 221).

: For moving subjects. Camera focuses continuously while shutter-

release button is pressed halfway; if subject moves, camera will engage predictive focus 
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; 

A

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.
