C.Fn II: Autofocus/Drive
C.Fn 6: Auto AF pt sel.:EOS iTR AF
Use this function to autofocus in viewfinder shooting by recognizing people. Applies when
the AF area selection mode is set to [
Manual select.:Zone AF ], [ Manual select.:Large
Zone AF ], or [ Auto selection AF ].
0:EOS iTR AF (Face priority)
Faces are given greater priority than with [ 1:Enable ] when the camera selects AF points
automatically.
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 first.
2:Disable
AF points are automatically selected based only on AF information.
Caution
With a setting of [ 0:EOS iTR AF (Face priority) ] or [ 1:Enable ], focusing will take
slightly longer than with setting [ 2:Disable ].
Even with a setting of [ 0:EOS iTR AF (Face priority) ] or [ 1:Enable ], the expected
result may not be obtained depending on the shooting conditions and subject.
Under low light, where external Speedlites for EOS cameras automatically emit an
AF-assist beam, AF points are selected automatically based only on AF
information. (Information on recognized people is not used for AF.)
