Using AF to Focus (AF Method)
The dedicated AF sensor is used to focus in One-Shot AF mode, using
the same AF method as with viewfinder shooting.
Although you can focus the target subject quickly, the Live View image
will be interrupted momentarily during the AF operation.
You can use nine AF points to focus (automatic selection). You can also
select one AF point to focus and focus only the area covered by that AF
point (manual selection).
