4. Flashgun instructions to the camera
31
The mecablitz transmits different signals and mes-
sages to the camera when it is connected to the
camera and is switched on.
4.1 Flash-ready indication
The orange 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 readiness
signal is transmitted to the camera where it is
indicated by a corresponding display in the camera’s
viewfinder. On some cameras (depending 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 camera’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 1/250th second, depending on the camera
model. Please refer to the camera’s operating
instructions for further details.
4.3 Correct-exposure indication (see fig. 3)
The green 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.
