9 Special functions
Depending on the camera model or camera
group, various special functions are availa-
ble.
For this purpose, data exchange must first
occur between the flash unit and camera to
access and set the special functions, for
example by tapping the shutter release.
The setting must occur immediately after
accessing the special functions since other-
wise the flash unit automatically switches
back to normal flash operation after a few
seconds!
9.1 Motor zoom reflector („Zoom“)
The motor zoom reflector of the flash unit
can illuminate lens angles from 24 mm (35
mm format).
Thanks to the use of the integrated wide-
angle diffuser
ቪ, the illumination widens to
12 mm.
Auto zoom
The zoom position of the reflector is automa-
tically adjusted to the lens focal length when
the flash unit is used with a camera that
transmits the data related to the lens focal
length. After the flash unit has been switched
on, „Zoom“ and the current zoom position of
the reflector are shown in the display.
Automatic adjustment occurs for lens focal
lengths from 24 mm.
The automatic adjustment will not be activat-
ed if the reflector is swivelled, if the wide-
angle diffuser
ቪ is pulled out, or a

Manual flash exposure correction is only pos-
sible in TTL flash mode if the camera sup-
ports this function (consult the camera’s ope-
rating instructions)!
If the camera does not support this function,
the adjusted correction will have no effect.
For some camera models, the manual flash
exposure corrections must be adjusted on
the camera. If this is the case, no correction
value will appear on the flash unit display.
After the shot, remember to cancel the manu-
al flash exposure correction in the camera!
Strongly reflecting objects in the motif can
have a negative impact on the camera’s
automatic exposure. The photograph will be
underexposed. Remove reflecting objects or
set a positive correction value.
