Is this cord copatable with a Novatron system and a Canon 5D II?
I'm not quite sure, to tell you the truth because I have not tried it on a 5D Mark II. I actually bought it for my Canon 7D for the sole intention of synching it up to a Quantum Flash, but it didn't work. However, it did work on my Olympus, though. So, in other words, if it didn't work for my Canon 7D, it probably won't work for you either; don't waste your money.
