Cordless SLAVE operation
Controllo SLAVE senza cavi
Funcionamiento esclavo sin cable
The SLAVE mode permits cordless,delay-free remote
triggering of several additional SLAVE or servo flash
units.Advantages for the photographer:
- Mobile use of several flash units
- No synch cable connection with the camera
- Modelling illumination
The SLAVE or servo flash unit is triggered by a light pulse
emitted by the on-camera „master“ flash unit (controller):
Actuation of the shutter release triggers the SLAVE or ser-
vo flash unit and the on-camera „master“ (controller)
simultaneously. SLAVE or servo flash unit and „master“
must all be ready for firing at the time of exposure (illumi-
nated flash-ready signal).
To ensure reliable operation the sensor in the SLAVE or
servo flash unit must receive sufficient light from the on-
camera „master“! In the event of malfunction it may be
necessary to change the position of the SLAVE or servo
flash unit so that the sensor receives more light. Since the
focal length adjusted on the lens is not automatically
transmitted to the SLAVE or servo flash unit it is advisable
to operate these units with the wide-angle diffuser (W) to
ensure uniform illumination of the subject with a wide
image-angle coverage.
