Sonia Optical Slave Trigger Rotating Hot Shoe

This optical slave trigger works well with all flash models EXCLUDING Canon EX. It has:
 
A 360 degree rotating hot shoe for complete directional control of flash and sensor. Two female PC sockets for connecting additional flashes with additional cords (not included).
Hot shoe on top and cold shoe fitting with standard 0.25 inch female thread on the bottom.
The slave requires no additional power, and accepts flash sync voltages up to 400V DC.


Important notice 
Any optical slave can be fooled into early triggering if your master flash produces a pre-flash, for white balance adjustment or red eye reduction, for example. In many cases, this pre-flash can be turned off, thereby avoiding the problem.
