f: Selecting the AF OperationN
Suited for still subjects. When you
press the shutter button halfway, the
camera will focus only once.
When focus is achieved, the AF point
that achieved focus will be displayed,
and the focus indicator <o> in the
viewfinder will also light up.
With evaluative metering (p.117), the
exposure setting will be set at the
same time as focus is achieved.
While you hold down the shutter button halfway, the focus will be
locked. You can then recompose the shot if desired.
This AF operation is suited for moving subjects when the focusing
distance keeps changing. While you hold down the shutter button
halfway, the camera will keep focusing on the subject continuously.
The exposure is set at the moment the picture is taken.
When the AF area selection mode (p.79) is set to 61-point automatic
selection AF, focus tracking will continue as long as the Area AF
frame covers the subject.
