Auto zoom
The zoom position of the main reflector
ቫ is automatically 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 cur-
rent zoom position of the main reflector
ቫ are shown in the display.
Automatic adjustment occurs for lens focal lengths from 24 mm. If a focal length
of less than 24 mm is used, „24“ flashes in the display as a warning that the shot
cannot be completely lit.
If so desired, the position of the main reflector
ቫ can be manually adjusted in
order to achieve particular lighting effects (such as spot effect etc.).
Manual zoom mode
For cameras that do not transfer any data regarding the focal length (e.g. when
using a manual focus lens), the zoom position of the main reflector must be adju-
sted to the lens focal length. In this case auto-zoom mode is not possible! After
switching on the flash unit, „Zoom“ appears in the display and the current zoom
position of the main reflector
ቫ appears.
Setting procedure
• Press button combination „Select“ until „Zoom“ appears flashing next to the
zoom position (mm).
• Apply the setting desired with the buttons ( + ) and ( - ). The flashing display
changes to „M.Zoom“ for manual zoom mode. The following zoom positions
are possible for the main reflector:
24 - 28 - 35 - 50 - 70 - 85 - 105 mm (35 mm format).
The setting takes effect immediately. After about 5 seconds the display stops
flashing and the setting is saved automatically.
When the camera transmits the lens focal length to the flash unit and a
manual zoom setting results in the shot not being completely lit by the
main reflector (for example, spot effect), the display of the zoom position
of the main reflector flashes as a warning! ☞
Tip:
If you do not necessarily need the full guide number and maximum flash range
of the flash unit, you can leave the zoom reflector at the position for the shortest
focal length of the zoom lens. This will provide full light coverage of the picture
and eliminate the need to continually adjust it to the focal length of the lens.
Example:
You use a zoom lens with a focal length range of 35 mm to 105 mm. In this
case, you set the position of the main reflector of the flash unit to 35 mm.
Resetting to auto-zoom
• Touch the shutter release to begin a data transfer between the flash unit and
the camera.
• Press the button combination „Select“ until „M.Zoom“ appears flashing next to
the zoom position (mm).
• Press the button ( + ) until the 105 mm position has been exceeded. The flas-
hing display „M.Zoom“ changes to „Zoom“ (= auto-zoom mode) and the
zoom position of the main reflector
ቫ is automatically adjusted to the lens
focal length. The setting takes effect immediately. After about 5 seconds the
display stops flashing and the setting is saved automatically.
The return from manual zoom mode to auto-zoom mode also occurs if the
flash unit is switched on again with the main switch
ቢ.
Wide-angle diffuser
With the wide angle diffuser
ቩ, focal lengths of 18 mm or more can be illumi-
nated (35 mm format).
Pull the wide-angle diffuser
ቩ out from the main reflector as far as it will go, and
then release it. The wide-angle diffuser ቩ automatically folds downwards. The
main reflector ቫ automatically moves to the required position. The distance rea-
dings and the zoom value are corrected to 18 mm on the display panel.
To insert the wide-angle diffuser
ቩ, turn it upwards 90° and push it all the way
in.
