5.7 Motor zoom reflector
The reflector of the mecablitz 44 AF-3N provides full
light coverage for focal lengths down to 28 mm,
whereas the reflector of the mecablitz 44 AF-4N
covers focal lengths as of 24 mm (35 mm format).
5.7.1 “Auto Zoom” (Fig. 32)
If the mecablitz is operated with a Group A came-
ra with CPU lens, its zoom reflector position will
be automatically adapted to the focal length of
the lens. When the mecablitz is turned on, the LC
display will indicate “Auto Zoom” and the current
reflector position.
Automatic reflector adaptation commences with
focal lengths as of 24 mm or 28 mm respectively.
If a lens with a focal length of less than 24 mm or
28 mm is used, the value “24” mm or “28” mm
will start to flash on the LC display to warn you of
vignetting because the mecablitz will not fully illu-
minate the picture right out to the image corners.
For lenses with focal lengths as of 20 mm a
wide-angle diffuser can be used (optional
extra, see section 7). The flash head must
then be set to the 24 mm or 28 mm position.
5.7.2 Manual zoom mode “M. Zoom” (Fig. 33)
With Group B cameras, or when a lens without
CPU is used (e.g. manual focus lens), it is neces-
sary to adjust the flash reflector’s zoom position
manually to the focal length of the lens. In this
case, auto-zooming is not possible. The LC dis-
play of the mecablitz indicates “M.Zoom” (for
manual zoom setting) and the current zoom posi-
tion (mm).

The following reflector positions can be selected
by repeated depression of the “Zoom” key:
24mm (only 44 AF-4N) - 28mm - 35mm - 50mm -
70mm - 85mm - 105mm.
No warning is given if the zoom reflector setting
is incorrect!
If you do not always need the full guide
number and maximum flash range of the
mecablitz 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 image corners and elimi-
nate the need for permanent adaptation to
the lens focal length.
