If the shot was correctly exposed in TTL flash mode, then the LC display illu-
mination will be activated during „o.k.“ display (see 4.1.3).
5.6 Motor zoom reflector
The reflector of the flash unit provides full light coverage for lenses of 24 mm
focal length and longer (35 mm format).
5.6.1 „Auto-Zoom“
If the flash unit is operated with a camera that transmits the focal length data
to the flash unit, then the zoom reflector position will be automatically adapted
to the focal length of the lens. When the flash unit is turned on, the LC display
will indicate „Auto Zoom“ and the current reflector position.
Automatic reflector adaptation commences with lenses of 24 mm focal
length. If a focal length shorter than 24 mm is used, then the „24“ indicated
on the LC display will start to flash as an indication that the flash unit cannot
fully illuminate the shot right out to the image corners.
A wide-angle diffuser (optional extra, see section 7) can be used for
lenses as of 20 mm focal length. In cases where the motor zoom re-
flector of the flash unit is automatically controlled by the digital ca-
meras Dimage 5, 7, or 7i, the focal length position of the reflector can
deviate from the focal length set on the lens. This is because the ca-
mera positions the reflector so that the flash coverage is larger than
necessary in order to guarantee a complete illumination of the picture
(comparable to the extended zoom mode described in section 5.6.3).
5.6.2 Manual zoom mode „M.Zoom“
The position of the zoom reflector can also be manually changed, for in-
stance to achieve specific lighting effects (e.g. hot-spot, etc.). Repeated de-
pression of the „Zoom“ key on the flash unit will successively select the fol-
lowing reflector positions:
24 mm - 28 mm - 35 mm - 50 mm - 70 mm - 85 mm - 105 mm
The LC display of the flash unit indicates „M.Zoom“ for manual zoom setting
and the current zoom position (mm). The setting becomes instantly effective.
The display is switched back to its normal state after approx. 5 sec.
☞
If manual adjustment of the zoom reflector results in a setting in which
the shot will not be fully illuminated right out to the image corners,
then the reflector position indicated on the display of the flash unit will
start to flash as a warning.
Example:
• You are using a lens focal length of 50 mm.
• A reflector position of 70 mm has been manually adjusted on the flash unit
(„M.Zoom“ is displayed).
„70 mm“ for zoom position will start to flash on the LC display of the flash
unit because the shot will not be fully illuminated right out to the image cor-
ners.
Returning to „Auto-Zoom“
There are various ways to return to „Auto Zoom“:
• Continue pressing the „Zoom“ key on the flash unit until „Auto Zoom“ ap-
pears on the display. The setting becomes instantly effective. The LC display
is switched back to its normal state after approx. 5 sec.
Or:
• Briefly turn off the flash unit by its main switch. When the flash unit is
turned on again the display of the flash unit will indicate „Auto Zoom“.
5.6.3 Extended zoom mode
The extended zoom mode (Ex) reduces the focal length setting of the flash
unit by one step compared with the focal length of the camera’s lens! The
resulting wider light coverage inside rooms provides additional stray light
(reflections) to achieve softer flash illumination.
Example of extended zoom mode:
The focal length set on the camera lens is 35 mm. The extended zoom mode
sets a 28 mm reflector position on the flash unit even though 35 mm conti-
nues to be indicated on the LC display!
