The Wein Combination Slave & Replacement Foot for Vivitar 283 & 285HV is a robust upgrade for the Vivitar 283 & 285HV's hot shoe that also adds the versatility of remote triggering. It slides onto any flash foot with no other connection necessary; the built-in optical slave has a 150' (45.8 m) range. Special hardware needed to attach the slave to the Vivitar foot as a permanent reinforcement is included, and no rewiring or factory service for the Vivitar will be necessary. This is a sensible upgrade for anyone making a living with their trusty Vivitar 283 or 285HV flash.
The Combination Slave/Replacement Foot has a built-in female "household" socket, the one connection which never seems to accidentally disconnect and cause you to miss a shot. The optical slave is disabled whenever a male household cord is affixed to the female household socket.
The housing is made of aircraft aluminum and has a 1/4-20" threaded female socket underneath for mounting upon tripods and light stands.
