I'm thinking about off-camera flash. Problem is all my flashes are elderly - Olympus T30, Vivitar 283 (with big voltage), and a couple of others. Does anyone have any recommendations for a (cheap) wireless system that will stand the big shoe voltages as I don't want to spend out on new flash units? Alternatively I could make a little adapter that slotted between receiver and flash to tame the trigger voltage if someone can give me some guidance on the components.
or I could just buy one ofthese cheap units and see if it blows up!
