Canon 7D Overheating Tip
I was shooting some interviews yesterday and after about an hour and a half of straight shooting I got the dreaded overheating warning and recording stopped on my 7D.
I gave it a rest for a few minutes, several times, to no avail. And then I swapped out the hot CF card (it was very hot) with a cool one. And boom, I was back to shooting.
I hope this is a real solution and can help others.

Wow that sounds like a great tip, I hope others find it works for them too!

Perhaps inconvenient, but using 4 gig cards could be an option. More card changes, less data that could be lost per card, cheaper to buy more cards. Less heat. Maybe it’s the heating of the card after all, and not the sensor as we all assumed.

I think it is a combination of the sensor and the card. Once I had left the 7D and LCD on during a setup, about 30 minutes, and the overheating began within about 30 minutes of shooting. The shoot yesterday was a good 90 minutes before the overheating started.
I’ll be shooting another interview on Tuesday and I’m sure I’ll get overheated again. I’ll do the card swap again and report back.

Not sure about that…
I’m working out dropped frams that i have on a 8 gig card.
I suspect the card is not fast enough.
(Don’t let the datarate fool you, specs on cards are not met, and peaks will occur in H264)Bigger cards are faster, so now i’m testing with 32 gig cards, hope that solves the problem.

Anyone know does the 5d overheat the same or is it better or worse?

Just a quick report. I shot an hour long interview yesterday and NO temp warning. Darn!

Shooting out in the arid desert gives us the same issues. While shooting outdoors at a brisk 95 degrees, we got shut down every 20-30 minutes. We wound up holding the camera in the stream of a car’s A/C – seems to work best by pointing the air just to the left of center (as you’re looking at the front of the camera) and taking the lens off and putting the cap on the body. I don’t know what having the lens on does differently, but it seemed faster by a few minutes. Maybe the lens heats up, too. I’ll try removing the card next time, too.
Maybe a heat sink or a small low power fan?

I have a 7D and use a battery grip with AA cells (6) 32Gig card and shoot till the card fills during interviews, never overheated and I live in Scottsdale AZ, quite hot here!
One idea about the “overheating” issues is when any battery drains, it get hot, if the batter is inside the camera the heat is transferred into the camera, by using the battery grip the heat stays outside of the camera, using the “dummy” battery with a cable will accomplish the same thing.

I use both canon 5d Mark II and the 7D as part of my three camera set-up for shooting interviews. I only get an hour with the 7D live view or recording. The 5D I have shot for 10 hours strait and never had a heat problem, just the annoying 12.5 minute record time and of course having to switch cards. I use all 32gig cards. But the 7D it does not matter If I switch cards or not I still have heat issues. I was wondering if maybe there is a way to add a cooling system to it.
