a8: AF Activation

G button A Custom Settings menu

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.
