7D Shut Down

Lupo Lobo , Nov 22, 2010; 11:49 p.m.

While shooting some casual photos today I noticed some odd behavior on my 7D. On trying to review a couple of photos I noticed the camera didn't respond and and nothing displayed on the LCD. I took 3 or 4 more photos and then the camera went dark, as if it had been powered off. I removed all batteries for about twenty minutes Then powered it back up and I was able to view images on the LCD again. I called it a day for that camera and put it away to use another body.

The only thing that I did different today was that I had my 580EX flash attached for fill light. I usually don't use flash with this camera. I did check the batteries and both were at about 57% (I use a battery grip on this camera). I also did have some card read errors a couple weeks ago but powering the camera off and back on seemed to resolve that. It doesn't seem likely that a faulty card would power off the camera - I am using San Disk if that is important.

Has anyone seen this behavior before? Any help would be appreciated.

I've own a 7D for over a year and nothing like this has happened. I'd reset the PRAM by removing both backup and mains. Removing the mains is not enough. Then I'd use a different CF card. If that doesn't cure it, you need Canon Service to pull 'n replace boards...

Thanks Puppy Face - I have had mine about the same length of time as well. I didn't make it clear above but yes I reset the PRAM. I am running some test shots on it now and it seems to be working so far, however whatever it was that happened earlier today is slightly disturbing. I will have to keep an eye on it for now - oh yeah I need to attach the flash and try that again just to make sure that the flash was not involved in the problem.

Didn't have quite the same problem. The 7D had problems focusing, intermittently the shutter release wouldn't work, and the quick control dial stopped working. Some confusion when connected to 550 EX flash. Had to go to Canon. They fixed it under warranty. Works fine now. Might be worthwhile at least to contact Canon: maybe there are some issues with the camera. Looks like the latest firmware is 1.2.2 - you might want to check if you need an update (my inner cynic thinks that they may fix stuff they don't tell you about). Cheers
