AF-Assist Beam Firing

You can enable or disable AF-assist beam firing of the camera or a Speedlite for EOS cameras.

  1. Select [Autofocus: AF-assist beam firing].

  2. Select an option.

    • [ON] Enable

      Enables firing of the AF-assist beam, when needed.

    • [OFF] Disable

      Disables firing of the AF-assist beam. Set if you prefer not to fire the AF-assist beam.

    • [LED] LED AF assist beam only

      Enables LED AF-assist beam firing by Speedlites equipped with this feature, when these flash units are attached. If your Speedlite is not LED-equipped, the camera's AF-assist beam is fired instead.


  • Speedlite AF-assist beam firing is disabled when the Speedlite's [Autofocus: AF-assist beam firing] Custom Function is set to [Disable].
