Metz MECABLITZ 34 AF-3 N, Operating Instructions Manual

Page: 28 / 128

4. Flashgun instructions to the camera
The mecablitz transmits different signals and
messages to the camera when it is connected to
the camera and is switched on.
4.1 Flash-ready indication
The green light on the mecablitz illuminates
when the flash capacitor is fully primed, thereby
indicating flash readiness. This means that flash
can be used for the next exposure. The flash rea-
diness signal is transmitted to the camera where it
is indicated by a corresponding display in the
camera’s viewfinder. On some cameras (depen-
ding on the model) the shutter is automatically
changed to flash sync speed when flash readiness
is reached. The flash will not be fired if the shutter
is released before the flash ready light illuminates
with the result that the exposure may be incorrect
if the camera control circuit has already changed
over to flash sync speed. Please refer to the came-
ra’s operating instructions for further details.
4.2 Automatic flash sync speed control
Most system cameras automatically change to
flash sync speed when flash readiness is reached.
The flash sync shutter speeds may vary between
1/30th and 1/300th second, depending on the
camera model. Please refer to the camera’s opera-
ting instructions for further details.
4.3 Correct-exposure indication (see fig. 4)
The red correct exposure light briefly illuminates
when flash exposure was correct. At the same
time the mecablitz sends an o.k. signal to the
camera for display in the viewfinder. Please refer
to the camera’s operating instructions for further
details.
