Choose whether the shutter-release button can be used to focus
(Shutter/AF-ON) or if focus can only be adjusted using the AF-ON
button or other controls to which AF-ON has been assigned
(AF-ON only).
Highlighting AF-ON only and pressing 2 displays
an Out-of-focus release option; select Enable to allow pictures to
be taken without focusing, or Disable to prevent the shutter being
released before the camera has been focused using the AF-ON
control.
To take pictures when Disable is selected, use the AF-ON
control to focus and press the shutter-release button all the way
down to release the shutter.
Note that Disable only applies if
Focus is selected for Custom Setting a1 (AF-C priority selection)
or a2 (AF-S priority selection) and an option other than auto-area
AF is selected for AF-area mode (0 104).
Choose the AF-area modes that can be
selected using the AF-mode button and sub-
command dial in viewfinder photography
(live view is unaffected; 0 104).
Highlight the
desired modes and press 2 to select or
deselect.
Press J to save changes when
settings are complete.
