Using AF to Focus
For very precise focusing, mount the camera on a tripod and magnify the
picture. Then focus manually. (p.110)
You can also use AI Servo AF or automatic/manual AF point selection.
However, if the AF point doesn’t cover the subject, you might not obtain
the desired focusing result.
You cannot take a picture during autofocusing. Take the picture only
while the Live View image is displayed.
The exposure will be set with focusing frame-linked evaluative metering.
(The metering cannot be linked with an AF point.)
