Custom Function Setting Items

Custom Functions are organized into three groups based on the type of function: C.Fn I: Exposure, C.Fn II: Autofocus/Drive, C.Fn III: Operation/Others.

C.Fn I: Exposure

C.Fn 1: Exposure level increments

Sets 1/2-stop increments for the shutter speed, aperture value, exposure compensation, AEB, flash exposure compensation, etc.

0:1/3-stop
1:1/2-stop

Note

When set to [1:1/2-stop], exposure level display is as follows.

C.Fn 2: ISO expansion

Makes “H” (equivalent to ISO 25600) available as an ISO speed you can set. Note that “H” is not available when [ Shooting : Highlight tone priority] is set to [Enable] or [Enhanced].

0:Disable
1:Enable

C.Fn 3: ISO speed setting increments

You can change the manual ISO speed setting increments to a whole-stop.

0:1/3-stop
1:1-stop

Note

Even if [1:1-stop] is set, ISO speed will be automatically set in 1/3-stop increments when ISO Auto is set.

C.Fn 4: Safety shift

You can shoot with the shutter speed and aperture value automatically adjusted to enable standard exposure if standard exposure would not be available under your specified shutter speed or aperture value in or mode.

0:Disable
1:Enable

C.Fn 5: Exposure comp. auto cancel

0:Enable

When you set the power switch to , the exposure compensation setting will be canceled.
1:Disable

The exposure compensation setting will not be canceled even if you set the power switch to .

Note

The exposure compensation setting is not canceled after auto power off, even when set to [0:Enable].

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.)

C.Fn 7: AF area selection method

0:→AF area selection button

After you press the or button in viewfinder shooting, pressing the button changes the AF area selection mode. In Live View shooting, pressing the button changes the AF method.
1:→Main Dial

After you press the or button, turning the dial changes the AF area selection mode.

Note

When [1:→Main Dial] is set, use the keys to move the AF point horizontally.

C.Fn 8: AF point display during focus

You can set whether to display AF points during AF point selection, before AF begins (shooting standby), when AF begins, during AF, and when subjects are in focus.

AF point display during focus	AF point selected	Before AF (shooting standby)	During AF	Focus achieved
○: Displayed, ×: Not displayed
0:Selected (constant)	○	○	○	○
1:All (constant)	○	○	○	○
2:Selected (pre-AF,focused)	○	○	×	○
3:Selected AF pt (focused)	○	×	×	○
4:Disable display	○	×	×	×

C.Fn 9: VF display illumination

0:Auto

The AF points achieving focus in low light or with a dark subject will automatically light up in red.
1:Enable

The AF points light up in red regardless of the ambient light level.
2:Disable

The AF points do not light up in red.

Note

When you press the or button, the AF points will light up in red regardless of this setting.
The aspect ratio lines, electronic level, and grid in the viewfinder will also light up in red.

C.Fn 10: Mirror lockup

You can prevent the camera vibration blur due to the mechanical vibrations (mirror shock) inside the camera during shooting with super telephoto lenses or shooting close-ups (macro photography). See Mirror Lockup for the mirror lockup procedure.

0:Disable
1:Enable

C.Fn III: Operation/Others

C.Fn 11: Warnings Warning icon in viewfinder

1:Previous display status
