Does anyone know of a way to get rear-curtain synch of studio flash with Canon 5D2? I can trigger the lights with on-camera flash which has that option, but optical slaving is very unreliable outdoors. I’d prefer to use radio, but I have not figured out a way to do that. Suggestions on either settings or equipment would be much appreciated!
(On Sony A7R is turned out to be a simple menu selection.)
