AF-ON Buttons, Predictive Focus Tracking, C2-AE-L/AF-L

The AF-ON Buttons

For the purpose of focusing the camera, pressing either of the AF-ONbuttons has the same effect as pressing the shutter-release button halfway (the AF-ONbutton for verti- cal shooting can only be used when the shutter-release button for vertical shooting is unlocked).

Predictive Focus Tracking

If the camera autofocus system detects that the subject is moving when the shutter- release button is pressed halfway, it will automatically initiate predictive focus tracking. If the subject is moving toward or away from the camera, the camera will track focus while attempting to predict where the subject will be when the shutter is released. In single-servo autofocus, the camera will initiate predictive focus tracking if the subject was moving when the shutter-release button was pressed halfway. Focus will lock when the subject stops moving. In continuous-servo AF, the camera will also initiate predictive focus tracking if the subject starts moving after the shutter-release button is pressed halfway. Focus will not lock when the subject stops moving.

Predictive focus tracking is not available in manual focus mode.

a1—AF-C Mode Priority ( 174)

If Focus is selected for Custom Setting a1 (AF-C mode priority), photographs can be taken in continuous servo-AF only when the camera is in focus. Select FPS rate + AF for improved focus during continuous shooting.

a2—AF-S Mode Priority ( 174)

If Release is selected for Custom Setting a2 (AF-S mode priority), photographs can be taken in single servo-AF even when the camera is not in focus.

a5—AF Activation ( 177)

If AF-ON only is selected for Custom Setting a5 (AF activation), the camera will only focus when one of the AF-ONbuttons is pressed, not when the shutter-release button is pressed halfway.

a8—Vertical AF-ON ( 179)

Custom Setting a8 (Vertical AF-ON) controls whether the AF-ONbutton for vertical shooting is used to initiate autofocus, select the focus area, or both.

c2—AE-L/AF-L ( 186)

If desired, the AE-L/AF-Lbutton can perform the same function as the AF-ONbutton.
