7d overheating warning

What were you shooting (how long, what format, location details, etc)?

I had it come up only once - we were shooting in a VERY small room, 5 people in there, AC turned off, 650w and two 300w lights going... everyone was sweating bullets - must have been in the 90s easily in there - and after about 45 minutes of continuous shooting we had the heat warning come up on both 7Ds we were shooting with (shooting 1080/24p).

I've since shot about 8 different jobs with the 7D, never had it happen again.
Shot about 90minutes of footage continuous footage just last week and I had no problems.
 
I had it happen when shooting my first commercial it was prob. 98 deg. florida humidity, and I had it sitting on my crane waiting to be used... it has to do with the new weather sealing...
 
Being from AZ this is a problem we deal with all the time. Keep this camera shaded when not in use. This is a good practice for all cameras. An umbrella on a c-stand or a space blanket should do the trick.
 
I did a little test with my new 7D. 29:59 at 480p @ 60...when it automatically stopped at 4GB, I started a 1080p @ 24...when it automatically stopped at 4GB (oddly only 11:14), I started a 720p @ 60 that started the heat warning flashing at 7:30 in. Shut off the camera for four minutes to let it cool off and started a 1080p @ 24...when it automatically stopped at 4GB (11:42 this time), I started another 1080p @ 24. This one ran and automatically stopped (I'm not sure how long this one ran to get to 4GB) with no heat warning, so I started a 730p @ 60...the heat warning came on at 3:42.

Camera was powered by the A/C Adapter and this was done in my office at standard room temps. I think there's something about 720p @ 60 that heats the camera up. I'll only be using 720 when I want slomo from now on.
 
I've recently wrapped a shoot using the 7D, and we had repeated overheating warnings throughout.

But I completely expected it, and prepared for it.

I was in the Amazon jungle, filming peacock bass fishing on the Rio Negro. The temperatures each day were around 95 degrees, and easily 10 degrees warmer in the sun on the water. Shooting off and on for about 30 minutes at 60p would cause the overheating icon to appear. That's when I'd reach in my bag and grab the second 7D, which was always set to record 1080/24p. Only after long periods of shooting long clips in full sun would the 1080/24p camera flash the overheating warning.

I also found that switching out of Live View mode helped quite a bit. And, of course, turning off the camera whenever possible helps even more. So, while I did get plenty of overheating warnings, they never really created an issue for me as I expected and prepared for them.

I'll be compiling all of my 7D "in the jungle" experiences in the next few days. Stay tuned.

Thanks for the replies! I'm glad I'm not the only one..
Yes, I was shooting 720p@60fps for a good 20 minutes outside in the shade when the temp warning appeared. But yes, I do live in south Florida, so regardless of shade it was still pretty warm.
mhood, thanks for taking the time to test this out!
So apparently the best solutions to avoid over heating issues are:
-Avoid constant shooting in 720p@60fps
-Keep in shade
-Turn off when not in use
-Switch off liveview frequently
-Carry two cameras

Are we the victims of a factory fault? Or is this just a consequence of filming with the 7D in a hot environment?
 
It's completely logical but still kind of crazy how the temperature of your environment makes the 7d reach overheating faster if at all.

It happened on a shoot today. HMC150 kept on rocking. It was a moderate shoot and moderate FL temperatures. We'll see it things change cause now I see it as a speciality, insert type, short narrative camera almost exclusively...
 
The 7D appears to be more prone to overheating because it has dual Digic processors, and it's more environmentally sealed than the 5D was.
 
CPU heat sinks come to mind. I would LMAO if someone came up with a cooling solution. : )

Wonder if they planned the release taking into account the seasons. :D
 
Saturday I was shooting at 1080p/24 for less then an hour in an indoor theater at a comfortable temp. I had previously shot video with the 7D for hours during the same conditions with no problems. The difference Saturday was I had a 300 2.8 IS with the IS enabled. I think the extra power from the IS caused the overheating thermometer to come up and I had to shut down for a bit.
 
Well there's some serious things to consider now with this camera.... Not insurmountable, but ceratainly things to consider. It's also a bit disconcerting since the buzz on this camera is from the video side of things...
 
Thats why I have the GH1 as a backup camera when shooting with the 7D.
I also have my 7D on 2 min auto standby so if I leave the camera it shuts down.
 
Below freezing is about when electronics start getting wacky. The trick is not to let the camera get cold inside, through and through. If you start running it before you go outside it might hold up very well. These overheating issues might be a blessing in disguise for some scenarios. I am curious to find out.

I can see no reason for this other than condensation issues. If it were true, or at least universally true, then people wouldn't be overclocking their CPUs using liquid nitrogen!
