622C TRANSCEIVER FEATURES

Saving the Settings

• Most External Flash Menu settings (including AF-assist C.Fn) are saved automatically in

the Transmitter 622C. Each 622C holds its own Master values, and can change the

camera’s menu settings unexpectedly when mounted on the camera.

• Not stored are FEB, Zoom, E-TTL Fire ratio and Group C’s FEC, which revert to default

values on power-up.

AF-Assist Beam

Autofocus Assist

When using Autofocus under low-light, the AF-assist beam can be emitted automatically to make it

easier for the camera to auto-focus.

• Each 622C carries its own setting for the C.Fn 8 (or similar) enable/disable setting for

“AF-assist beam firing”.

• Set the value by placing a 622C on the camera’s hotshoe, and use the camera’s “External

flash C.Fn settings” menu to make the setting.

• The user must also enable the AF-assist beam in the camera, Set camera’s Custom

Function / Autofocus assist beam to “Enable” or “Only ext. flash”).

• This setting controls both the focus-assist and the confirmation indicator.

• The camera reads the setting from the 622C transmitter when a 622C is mounted.

• The 622C Transmitter will emit the beam when required by the camera.

• An on-TX flash which has an AF-assist beam function can also emit at the same time.

• Neither a remote 622C nor a remote flash will emit the A/F beam.

• The beam will not be emitted when Live mode or Face detection mode is used.

• The LED laser provides a bright pattern effective up to 4 metres. There is no health risk.

Menu Setting Confirmation

When a change in the camera menu is successfully applied to a remote Class 1 flash, the remote

622C’s AF-Assist Beam will flash twice when the [Set] button is pressed

• The confirmation light will be emitted only if the remote 622C has C.Fn 8 enabled.

Sleep Wakeup

• Issued on half shutter or [Test].

• Flash must be mounted on a 622C hot-shoe, not by a PC-sync cord.

• Flash must have a wake-up capability.
