Canon EOS Rebel T6i Telephoto Kit 业主指南

3 Custom Function SettingsK

340

Enables or disables the built-in flash’s AF-assist beam or the EOS-
dedicated external Speedlite’s AF-assist beam.
0: Enable

The AF-assist beam will be emitted when necessary.

The AF-assist beam will not be emitted. This prevents the AF-
assist beam from disturbing others.

If an external Speedlite is attached, it will emit the AF-assist beam 
when necessary. The camera’s built-in flash will not fire the AF-
assist beam.

When an external Speedlite is attached, only the infrared AF-assist 
beam will be emitted. Set this when you do not want the camera to 
fire the AF-assist beam 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.

You can set the method for changing the AF area selection mode.
0: S 9 AF area selection button

After you press the <S> or <B> button, each time you press the 
<B> button, the AF area selection mode changes.

1: S 9 Main Dial

After you press the <S> or <B> button, turning the <6> dial 
changes the AF area selection mode.

If the external Speedlite’s [AF-assist beam firing] Custom Function is set 
to [Disable], this function’s setting will be overridden and the AF-assist 
beam will not be emitted.
