Using AF to Focus (AF Method)
AF Operation
 
Even when focus is achieved, pressing the shutter button halfway 
will focus again.
 
The image brightness may change during and after the AF 
operation.
 
If the light source changes while the Live View image is displayed, 
the screen may flicker and focusing may be difficult. If this happens, 
exit Live View shooting and execute AF under the actual light 
source.
 
If [u+Tracking] is set, magnified view is not possible.
 
When [FlexiZone - Multi] is set and you press the <u> button, the 
center of the selected zone (or image center with automatic 
selection) will be magnified.
 
When [FlexiZone - Single] is set and you press the <u> button, 
the area covered by the AF point will be magnified. If you press the 
shutter button halfway, focusing will be performed while displaying 
the magnified view. If focusing is difficult in magnified view, return to 
the normal display and use AF. Note that the AF speed may differ 
between the normal and magnified views.
 
If you magnify the view after focusing with [FlexiZone - Multi] or 
[FlexiZone - Single] in the normal view, precise focus may not be 
achieved.
Notes for AF
 
When in magnified view, contrast-detection AF will be applied regardless 
of the lens used. The AF speed will therefore become slow.
 
When in magnified view, Continuous AF (p.294) will not be executed.
 
In magnified view, the image will be displayed without distortion 
correction applied.
