Was doing a shoot yesterday and 5D classic started acting weird, I took it to the camera shop and the menu won't come up and the shutter button don't work. What do think come be wrong? they couldn't figure out what was going on. I change the internal battery and updated the firmware, is there a way to reset it some how? By the way i got it used maybe the guy knew it was going out. Thanks in advance.

I can't help with the problem but I'm sure you'll have more luck if you post this in the Canon forum. It gets a lot more visitation.

Good luck.......Don
