Using Af To Focus - Canon EOS 50D Instruction Manual

Using AF to FocusN
Selecting the AF Mode
Three AF modes are provided: [Quick mode], [Live mode] (p.123),
and [Liveu mode] (face detection) (p.124). If you want to achieve
precise focusing, magnify the image and focus manually (p.127).
Quick mode
The dedicated AF sensor is used to focus in the One-Shot AF mode
(p.84) in the same way (AF method on p.84, 86) as with viewfinder
shooting.
Although you can focus the desired area quickly, the Live View image
will be interrupted momentarily during the AF operation.
