Power-Zoom
Automatic control of the motorized zoom
When using zoom lenses that transmit their
focal widths to the camera, the camera forwards
this information to the flash unit. Then the flash
unit automatically adjusts its zoom position.
The automatic reflector control of the motorized
zoom is possible with cameras that permit the
digital transmission to the flash unit.
The LCD display on the flash unit indicates zoom
positions of 24-28-35-50-70-85 mm. When the
flash unit is switched on, the zoom is activated
and the position is set at 35 mm. As soon as the
camera's release is touched only slightly, the
focal width of the flash unit is automatically
adapted to the focal width of the lens.
Whenever the flash head is not at the normal
setting (pointing forwards) whereby it is in
another position, the zoom position clicks to 50
mm and is indicated in the LCD display by a
short flash in the Auto mode.
Manual Control of the Motorized Zoom
With the "Zoom" button, you can alter the
reflector position of the zoom independently of
the focal width of the lens. The LCD display then
indicates "M" and the current setting of the
reflector's zoom position.
Light tapping of the "Zoom" button changes the
zoom position in this order: 24-28-35-50-70-85
mm.
Auto Zoom position: 24, 28, 35, 50, 70, 85 mm
zoom.
Receiver Function
This flash unit can be operated as a wireless
receiver by setting the switch "Slave Mode" to
the S position. The flash unit switches
automatically to the M mode with an energy
ration of 1:1 and a focal width of 24 mm. When
the sensor discovers the release of an extreme
flash, the flash is released simultaneously. The
quantity of the light emission can be selected by
setting the energy ration from 1/1 to 1/8. If
several flash units are used as receivers, then
the corresponding quantity of light must be
22
taken into consideration in order to calculate the
correct lighting. If the reception mode is
activated, the energy-saving mode does not
operate.
Energy-Saving Function
To save electricity, the flash unit automatically
switches off approximately 3 minutes after it has
been switched on or since the most recent flash
was released. The LCD display indicates the
"OFF" signal. To reactivate the flash unit, simply
press any button switch below the LCD display
table or switch the main switch off and back on.
The flash unit is not full switched off in the
energy-saving function setting, but its energy
use is drastically reduced. When you are no
longer using the flash unit, set the main switch
to "OFF".
