Lc Display Illumination; Motor Zoom Reflector; Auto-Zoom; Manual Zoom Mode „M.zoom - Canon metz 44 AF 4 c Bedienungsanleitung

5.5 LC display illumination (Fig. 2)
Keep the „Mode" or „Zoom" key depressed for approx. 10 sec. to activate
the LC display illumination of the flash unit. The LC display illumination is
switched off when a flash is triggered.
The settings on the flash unit are not changed when the above keys
are pressed for the first time!
If the shot was correctly exposed in TTL flash mode, then the LC display illu-
mination will be activated during „o.k." display (see 4.3).

5.6 Motor zoom reflector

The reflector's illumination angle equals the coverage of a lens of 24 mm fo-
cal length (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 adapt-
ed to the focal length of the lens. When the flash unit is turned on, the LC dis-
play 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" mm indicated on the LC dis-
play 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 and longer.
5.6.2 Manual zoom mode „M.Zoom"
The position of the zoom reflector can also be manually changed, for instance to
achieve specific lighting effects (e.g. hot-spot, etc.). Repeated depression of the
„Zoom" key on the flash unit will successively select the following reflector positions:
24 mm - 28mm - 35mm - 50mm - 70mm - 85mm - 105mm.
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.
70
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 1:
• 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 corners.
Example 2 :
• You are using a lens focal length of 50 mm.
• A reflector position of 35 mm has been manually adjusted on the flash unit
(„M.Zoom" is displayed).
• „35 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 corners.
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:
