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 Shutter-priority AE or Aperture-priority AE mode.

  • 0:Disable
  • 1:Enable

C.Fn 5: Exposure comp. auto cancel

  • 0:Enable

    When you set the power switch to Power off, 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 Power off.

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→AF area selection button

    After you press the AF area selection or AF point selection button in viewfinder shooting, pressing the AF area selection button changes the AF area selection mode. In Live View shooting, pressing the AF area selection button changes the AF method.

  • 1:AF area selection→Main Dial

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

Note

  • When [1:AF area selection→Main Dial] is set, use the Left key Right key 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.

○: Displayed, ×: Not displayed

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 AF area selection or AF point selection 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

The Warning icon icon can be displayed in the field of view of the viewfinder when any of the following functions are set ().

Select the function for which you want the warning icon to appear, then press SET to add a checkmark [Check]. Select [OK] to register the setting.

  • When monochrome set

    If the [Shooting: Picture Style] is set to [Monochrome] (), the warning icon will appear.

  • When WB is corrected

    The warning icon appears when white balance correction is set ().

  • When Multi Shot Noise Reduction is set

    If [Shooting: High ISO speed NR] is set to [Multi Shot Noise Reduction] (), the warning icon will appear.

Note

  • If you set any of the checkmarked [Check] functions, [Warning icon] will also appear for the respective setting displayed on the Creative Zone screen ().

C.Fn 12: Screen display when power ON

  • 0:Display on

    When you turn on the power, the Quick Control screen will appear ().

  • 1:Previous display status

    When you turn on the power, the camera starts up with the same screen display as before the power was turned off. For this reason, if you turn off the camera with the screen off, the screen remains blank the next time the camera is turned on, which helps conserve battery power. The menu operations and image playback will be available as usual.

C.Fn 13: Custom Controls

You can assign frequently used functions to camera buttons or dials according to your preferences for easy operations.

  1. Select a camera control.

  2. Select a function to assign.

    • Press SET to set it.

Note

  • With the screen in step 1 displayed, you can press the Erase button to restore the Custom Control settings to their defaults. [Custom Controls] settings are not cleared even if you select [Clear all Custom Func. (C.Fn)].

Caution

  • With auto power off, the lens will not retract regardless of the setting.
  • Before detaching the lens, make sure that it is retracted.
