operating instructions for the camera)!
The AF measuring beam is activated by the camera elec-
tronics when the ambient lighting conditions are insuffi-
cient 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). Low-
speed zoom lenses can significantly curtail the range of
the AF measuring beam.
Some autofocus cameras have several AF mete-
ring fields in addition to the central AF metering
area in the camera's viewfinder. The striped pat-
tern of the AF measuring beam only supports
the camera's central AF sensor. Consequently it
may be necessary to adjust the central AF sen-
sor manually on the camera (see the operating
instructions for the given camera and the SCA
adapter).
12. Special functions
The special functions of the mecablitz can be called, one
after the other, by depressing the Select button, and they
can be set, switched off and stored with the setting disk.
12.1 Bleep function
The bleep function
certain mecablitz functions. It enables the photographer
to concentrate fully on the subject without being distrac-
ted by the need to observe additional visual status dis-
plays!
The bleep function acoustically indicates the following:
• Flash readiness
• Correct flash exposure
• Automatic shut-off of the flash
• Incorrect operation
Acoustic signal after the mecablitz has been
switched on:
• A brief (approx. 2 sec.) uninterrupted bleep signal after
the mecablitz has been switched on indicates flash
readiness.
Bleep signals after exposure:
• A brief (approx. 3 sec.) uninterrupted bleep signal
immediately after shooting indicates that exposure
was correct and that flash readiness continues. If there
is no bleep signal immediately after shooting the pictu-
re was underexposed.
• An intermittent bleep signal immediately after shooting
confirms correct flash exposure, but flash readiness
