A Menu Function Settings

Live View shooting
You can set Live View shooting to [Enable] or [Disable].
AF method
You can select [u+Tracking] (p.153), [FlexiZone - Multi] (p.155),
[FlexiZone - Single] (p.156), or [Quick mode] (p.160).
Continuous AF
The default setting is [Enable].
Since the focus is constantly close to the subject, when you press
the shutter button, the camera quickly focuses the subject. If
[Enable] is set, the lens will operate frequently 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.
During Continuous AF, turn off the power before you set the lens's
focus mode switch to <MF>.
Touch Shutter
Just by tapping the LCD monitor screen, you can focus and take the
picture automatically. For details, see page 162.
Grid display
With [Grid 1l] or [Grid 2m], you can display grid lines to help
you level the camera vertically or horizontally.
