I've been having MAJOR problems with the Yongnuo YN-622C and my 580EX IIs. I have two 580EX IIs and both of them have now gone out on me, multiple times. One of them has gone out at LEAST 5 times. I'm honestly starting to lose track now. I keep sending them back to Canon for repair.
Anyways, after reading an article that was posted by a company that was doing testing for this same problem with Pocketwizards, I figured that it was an inherent problem with the 580EX II and using it with off-camera high-speed sync, or off-camera ETTL. The thing is, I wasn't using them with HSS, nor was I "cranking" away on them.
So anyways, I decided that I would try out the YN-622C on-camera, with the 580EX II on top of it. No HSS. No fast shooting. So just a basic pass-through mode, both of them mounted on-camera. STILL went out on me -- after ONE shot!! The 580EX II is doing the same thing.....AGAIN. It seems to be firing the pre-flash at full power and then the ETTL exposure comes out completely dark. Then, in manual mode, it fires full power.
Every time Canon repairs them, they say that they are replacing the battery housing and battery door......? What the heck. How could the YN-622C be causing this problem?
I'm BEYOND frustrated with this. I'm ready to throw those flashes in the garbage disposal.
