7D and Flash Issue
Aug 13, 2010

Over the past month I've done a couple of days of indoor shooting. Both times my 7D and 430EX stopped communicating with one another after around an hour or two. My shots suddenly became completely overexposed, and I had to un-attach and re-attach the flash to get it to work.

I was wondering if anyone else has gone through this, and if there is some underlying reason I am missing that may have caused this.

Thanks in advance
