Changing the Autofocus Mode

Selecting the AF Mode
The AF modes available are [Live mode], [u Live mode] (face
detection, p.132), and [Quick mode] (p.136).
If you want to achieve precise focus, set the lens focus mode switch to
<MF>, magnify the image, and focus manually (p.138).
Live Mode: d
The image sensor is used to focus. Although AF is possible with the

with the Quick mode. Also, achieving focus may be more difficult than
with the Quick mode.
