First, let me say that I know nothing about speedlights and off-camera flash photography.
I want to be able to use 3 off-camera speedlights (a 430EX, a 430EX II, and a 430EX III-RT) on a Canon 5DII, 5DIII (neither of which has an on-camera flash), or 7DII (has an on-camera flash).
What inexpensive (Yongnuo) equipment do i put in the hotshoe to make all 3 flashes fire in sync? Would I also need something on the 430EX and 430EX II, since they are not RT?
I'm at a loss of what I need to buy to make the 3 flashes fire off-camera. Something you suggest other than Yongnuo? I don't want to pay Canon prices for this.
Thanks,
Christne
