C.Fn II-12: Auto AF point selection: EOS iTR AF
Use this function to autofocus in viewfi nder shooting by recognizing people.
This function works when the AF area selection mode is set to Zone AF
(manual selection of zone), Large Zone AF (manual selection of zone), or
Automatic selection AF.

0: EOS iTR AF (Face priority)
Faces are given greater priority than with
[1:Enable]
when the camera
selects AF points.
In One-Shot AF mode, this makes it easier to focus on faces of still
human subjects in the AF area.
Also makes it easier to focus on faces in the AF area in AI Servo AF
mode.
Once focus is achieved, AF points are automatically selected to keep
focusing on the faces initially in focus.

1: Enable
The camera selects AF points automatically based on AF information and
information on recognized people.
In One-Shot AF mode, focusing on a still human subject in the AF area is
made easier.
In AI Servo AF mode, focusing on a human subject in the AF area is
made easier. If no people are detected, the camera focuses on the
nearest subject. Once focus is achieved, AF points are automatically
selected so that the camera continues to focus on the color of the area it
focused on fi rst.

2: Disable
AF points are automatically selected based only on AF information.

AF information. (Information on recognized people is not used for AF.)
