The settable functions on this menu screen apply only to Live View
shooting. They do not work with viewfinder shooting (settings
become invalid).
Live View shooting
You can set Live View shooting to [Enable] or [Disable].
AF method
You can select [u+Tracking], [FlexiZone - Multi], [FlexiZone -
Single] or [Quick mode]. See pages 233-244 for the AF method.

Continuous AF

The default setting is [Enable].
The camera attains rough focus of the subject continuously. This
makes it quicker to achieve focus when you press the shutter button
halfway. If [Enable] is set, the lens will operate constantly and
consume more battery power. This will reduce the number of
possible shots (battery life). Also, if the AF method is set to [Quick
mode], Continuous AF will be automatically set to [Disable]. If you
select another AF method, Continuous AF will revert to the original
setting.
If you want to set the lens focus mode switch to <MF> during
Continuous AF, first stop Live View shooting.

In Basic Zone modes, the [A2] tab and
certain options under the [A1] tab will
not appear.
