622 FEATURES

AF-Assist Beam
When using Autofocus under low-light, the AF-assist beam of the Transmitter will be emitted
automatically to make it easier to autofocus. An on-top flash which has an AF-assist beam function
can also emit at the same time.
•
The AF-assist beam can be enabled or disabled by the custom function setting of the
camera.
•
The LED laser provides a bright, clear pattern with a good range.
•
Neither a 622 Receiver nor an off-camera flash on the receiver will emit the beam.

Sleep Wakeup

•
On ½ shutter or [Test].
•
Flash must be mounted on hot-shoe, not PC-sync cord.
•
Flash must have a wake-up facility.

indicators.
•
