Well I was using a mates 580 EX II last night and I noticed something wierd. after the shot was taken my camera froze. It wouldn't even turn off.
This has never happened to me before. I have used a 420 EX lately and it has been fine. But now all of a sudden its starts freezing. its happened about 3 times now..
I'm just wondering if there are any known problems as to why this would happen..
