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 operating mode and camera 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
When the flash unit is on, the camera will automa-
tically switch it to flash sync speed from any ope-
rating mode selected. The sync speed depends on
the camera model and usually ranges between
1/30 sec. and 1/250 sec. For details please refer
to the camera’s instructions for use.
Some camera models will, when the flash unit is on,
switch it to flash sync speed as soon as program
mode „P“ or full-auto mode is selected. Speeds
faster than the flash sync speed cannot be set.
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.
