4. Motor-zoom control (auto-zoom)

Only with flash units featuring built-in motor zoom:
mecablitz 44 MZ-2, 50 MZ-5, 54 MZ-..., 70 MZ-...
and 76 MZ-5.
Flash coverage is automatically adapted to the
focal length of the camera lens.
After the flash unit has been switched on, the
"auto-zoom" function is instantly set if the camera
is on and activated by touching the shutter release.

5. AF measuring beam control

The AF measuring beam is activated by the camera
electronics when the ambient lighting conditions
are insufficient for automatic focusing. The AF
beam projects a striped pattern on to the subject,
and the camera uses this pattern to focus
automatically. The AF beam has a range of 9 m
(with a 50 mm f/1.7 standard lens).
Note:
To enable the camera to activate the AF measuring
beam, the lens must be set to AF and the camera
must be in the "Single-AF" or "ONE-SHOT-AF"
autofocus mode (see operating instructions for the
given camera).
Low-speed zoom lenses can significantly curtail
the range of the AF measuring beam!
The striped pattern of the AF measuring beam only
supports the central AF sensor of the camera. If
your camera has several AF metering areas, we
recommend to only activate the central one (please
refer to the camera's operating instructions).
