Setting Focus and Exposure with the AEL/AFL Button
(K AEL/AFL)
MENU G J [K AEL/AFL]
Choose how the camera sets focus and exposure when the shutter button or AEL/
AFL button is pressed. The camera normally focuses and locks exposure when the
shutter button is pressed halfway, but this can be changed according to the subject or
shooting conditions.
S-AF
Choose the focus or metering operation performed using the shutter or
AEL/AFL button (P. 202).
C-AF
MF
FAF
Half Way AF
Choose whether the camera focuses when the shutter is pressed halfway.
[Operative]: Pressing the shutter button halfway initiates autofocus
regardless of whether autofocus is currently assigned to the AEL/AFL
button. In [C-AF] mode, the last button pressed is used to maintain focus.
This option has no effect in [MF] or [FAF] mode.
[Inoperative]: Pressing the shutter button halfway will not initiate autofocus if
autofocus is currently assigned to the AEL/AFL button.
Face Priority
AF
Choose whether the AEL/AFL and shutter buttons perform the same or
different functions when faces are detected.
If [On] is selected, the camera will focus on faces or eyes when the AEL/
AFL button is pressed.
If [Off] is selected, the camera will instead focus on the current AF target.
