f: Changing the Autofocus OperationN
You can select the AF (autofocus) operation characteristics suiting the
shooting conditions or subject. In Basic Zone modes, the optimum AF
operation is set automatically for the respective shooting mode.

Suited for still subjects. When you press the shutter button
halfway, the camera will focus only once.
When focus is achieved, the dot inside the AF point achieving focus
lights up briefly in red, and the focus confirmation light <o> in the
viewfinder will also light up.
With evaluative metering (p.121), the exposure setting will be set at
the same time focus is achieved.
While you hold down the shutter button halfway, the focus will be
