Motor Zoom Reflector; Auto-Zoom; Manual Zoom Mode „M.zoom; Extended Zoom Mode - Metz MECABLITZ 44 AF-4 O Manual De Instrucciones

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 illumi-
nation will be activated during „o.k." display (see 4.3)..

6.5 Motor zoom reflector

The reflector's illumination angle equals the coverage of a lens as of 24 mm
focal length.

6.5.1 "Auto-Zoom"

If the flash unit is operated with a camera that transmits the data of the lens
focal length to the flash unit, its zoom reflector position will be automatically
adapted to the focal length of the lens. When the flash unit is turned on, its
LC display will indicate „Auto Zoom" and the current reflector position
(35 mm format).
Automatic reflector adaptation commences with focal lengths as of 24 mm
(35 mm format). If a lens with a focal length of less than 24 mm is used, the
value „24" mm will start flashing on the LC display to warn you of vignetting
because the flash unit will not fully illuminate the picture right out to the ima-
ge corners.
For lenses with focal lengths as of 20 mm (35 mm format) a wide-
angle diffuser can be used (optional extra, see section 8) The flash
head must then be set to 24 mm position.
6.5.2 Manual zoom mode „M.Zoom"
If required the reflector's zoom position can be manually changed to achieve
specific lighting effects e.g. hot-spot, etc.). Repeated depression of the
„Zoom" key (Fig.2) on the flash unit will successively select the following
reflector positions::
24mm - 28mm – 35mm – 50mm – 70mm – 85mm – 105mm.
The flash unit's LC display 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 seconds.
62
If manual adjustment of the zoom reflector results in vignetting so that
the flash will not cover the image corners, then the reflector position
indicated by the flash unit's display will start flashing 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 the zoom position starts flashing on the flash unit's LC display
because the image corners will not be fully illuminated.
Returning to "Auto-Zoom"
There are various ways to return to "Auto Zoom".
• Continue pressing the „Zoom" key
Zoom" appears in the display. The setting becomes instantly effective. The
LC display returns to its normal state after approx. 5 seconds.
Or:
• Briefly turn off the flash unit by its main switch
unit is turned on again its LC display will indicate „Auto Zoom".

6.5.3 Extended zoom mode

The extended zoom mode (Ex) reduces the focal length setting of the flash
unit by one step as compared to the focal length of the camera lens. The
resulting wider light coverage inside rooms provides additional stray light
(reflections) to achieve a 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 but 35 mm continues to be
indicated by the LC display.
The extended zoom mode is only possible in the „Auto Zoom" mode with
focal lengths as of 28 mm. Since the initital position of the zoom reflector is
24 mm, a focal length of less than 28 mm will cause „24" to flash on the
LC display thereby warning the user that the required reflector position for
the extended zoom mode cannot be set.
