4. Flashgun instructions to the camera
26
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 orange light on the mecablitz illuminates
when the flash capacitor is fully primed, thereby indi-
cating flash readiness. This means that flash can be
used for the next exposure. The flash readiness sig-
nal 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.
