Using Af To Focus - Canon EOS 5D Mark III Instruction Manual

Using AF to Focus

Selecting the AF Mode
The AF modes available are [Live mode], [u Live mode] (face
detection, p.210), and [Quick mode] (p.214).
If you want to achieve precise focus, set the lens focus mode switch to
<MF>, magnify the image, and focus manually (p.216).
Live Mode: d
The image sensor is used to focus. Although AF is possible with the
Live View image displayed, the AF operation will take longer than
with the Quick mode. Also, achieving focus may be more difficult than
with the Quick mode.

mode on the setting screen displayed.
