Canon 7D Overheating Tip
on Jun 26, 2010 at 6:20:30 pm

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.

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.

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

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?

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.

I've never seen a cooling system - I think mostly because that would require blowing air and, consequently, dust onto the sensor which is bad. I was thinking you could mount an aluminum heat sink (using a Canon mount) to the body and blow air across that (like a computer chip). Would work well with the 7D and 5D because they have metal frames (I may be wrong on the metal frame), but not so with the plastic frame cameras (like the T2i). I guess you could go to a computer store, buy an aluminum heat sink and attach it to a spare lens converter with JB Weld (or something) and try it.

Now I'm gonna have to try it! Gotta make sure no air can sneak in past the mount. May need a small, round piece of aluminum to mount to it first... dunno.

In the meantime, we used a car air conditioner, attached the body cap, and just held it in place. We had 2 cameras so while one was shooting, the other was cooling. This was in the middle of the summer here in Tucson and shooting during the day outdoors.

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.
