3 Customizing AF FunctionsN
Enables or disables the AF-assist beam from the EOS-dedicated
external Speedlite.
ON: Enable
The external Speedlite emits the AF-
assist beam when necessary.
OFF: Disable
The external Speedlite will not emit
the AF-assist beam. Prevents the AF-
assist beam from disturbing others.
IR: IR AF assist beam only
When an external Speedlite is attached, only the infrared AF-assist
beam will be emitted. This prevents the AF-assist light from firing as
a burst of small flashes.
With an EX-series Speedlite equipped with an LED light, the LED
light will not automatically turn on for AF-assist.
AF-assist beam firing
If an external Speedlite’s [AF-assist beam firing] Custom Function is set to
[Disabled], the Speedlite will not emit the AF-assist beam regardless of this
setting.
