Warning: Overheating

I read this on another forum and wondered if anyone else is having this experience with their 7D or 5D?

<At first, I had no problems with this, but today it's finally happened for the first time. I was in a room around 75 degrees F, and it overheated in less than ONE MINUTE. No exaggeration. It keeps happening too. Never Ever had this before and I've had it ever since Mid-October.... I wonder if I'm going to have to send it to Canon or something. I basically got it for video to.>
 
I encountered much more of the overheating than I expected but didn't notice any degredation in the footage shot while the warning was flashing. Every camera has a got'cha and this seems to be the 7D's. I hate it and wonder if newer versions suffer much less overheating as several folks have suggested. I'd really like to decide whether or not to keep the 7D I have before I glue an LCDVF mount on it.
 
My 7D has never over heated in such easy going situations... it did however, start blinking while it was on standbye for the next shot I was gonna shoot... but it was on a crane, on black new asphalt on one of the hottest days of the year in florida humidity. It has to do with the extreme weather proofing it is amazing, literally the first cam I have owned and wasn't afraid to go shoot uncovered in the rain. This thing was taken to the arctic circle and buried in the snow for days on end... http://www.canonrumors.com/2009/12/7d-antarctica/
 
My 7d overheated yesterday while doing some interviews. The camera had probably been going off and on for 2 hours and the room was probably 75ish degrees. If I turned the camera off, I would get some time without the blinking, but the camera started doing other funky things as well (would blink "err", which could be fixed my removing the battery). The overheating worries me a bit, but the room was to the point of being uncomfortable, so I'm not sure what will happen in other situations.
 
i've only had my 7d over heat once.. and that was when it was hanging from a lighting grid in a studio right next a about 1200w's of lights..

apart from that all good.

Sounds good Joe. I'm mostly planning to use the 7D for short clips. I was a bit worried before buying a 7d from some of the reports, but I think the problem comes simple things like leaving it on all day in a hot environment or near hot lights.
I also think if you power down between takes it will cool off.
The nice thing about the prism and mirror is you get to work with the camera through the lens when the camera is off. Those are two big advantages.
 
i was reading about this aday before i went to shoot along day of 10 interviews each one 30min
and i got scaerd so i broght with me dvx100 for safty
i am happy to inform you that the cam work great with no overheating at all
we were shoting indoor and the camera worked for 6h non stop

Ram, that sounds like good news. Did you ever turn off the camera during the day or was it on nonstop? What mode were you shooting in 1080p, 720p, and what frame rate, 24fps, 25fps, 30fps, 50fps or 60fps?
Also some people said the 7D they had that was overheating was one of the first units out. when did you get your 7D?
 
My 7D didn't overheat during a whole day shoot in 1080p but it does get hotter when using the 720p mode. It was in room temperature and the camera was put in standby during short breaks and I would recommend doing this whenever you have the chance to avoid overheating issues.
 
We just had a concertshoot with two 7Ds and they both went into overheating-mode rather soon. It was an indoor venue and rather warm, but not hot. still, rolling for 30 minutes and they were both in trouble. i took out the lens and battery for a minute and then got to shoot a few minutes again, before the warning light came on again. so indoors and in heat it is an issue.

at the same time i have shot several pieces outside and inside where the cam wasn´t rolling for such long periods and had no issues at all. so what´s a problem is the constant shooting-mode.
 
But what mode were you using? I think 50p/60p (in either standard-def or 720) is more prone to overheat than 1080/24 or 25. Were you using 720 or standard-def mode?
 
the camera was working non stop i turn it off a few times to change card/battery
i was shooting 1080 25p

i bought my just one month ago
 
My friend and I shot a feature in the freezing cold in NY a couple weeks ago and the warning came on twice. once in the subway and once in an office. Both times the environment wasn't hot. We were using the camera a lot but nothing insane. Is there any issue with the footage when the heat warning comes on? I believe it will just go till it gets too hot than the camera on its own will shut down....if I remember reading correctly. We were shooting 1080 24p the whole time.

All cameras with electronic sensors do, in some form or another. imagers operate best and with the least amount of interference when they're run cool, which is why Astronomy geeks cool their CCDs so they can take very long exposures of very faint objects. If you don’t cool it then you will go random noise that shows up as random pixels during your long exposures.

What serial numbers are your cams? I would think you will find newer cameras to be better in this regard. I have held off buying until this overheating thing is minimized. When I worked at Canon, they would constantly do small upgrades in parts without saying there were changes made. Often the part numbers would change the tenth placeholder to indicate a change even though they were interchangeable, and may not be able to visablly tell a difference. In some cases a problem such as this could include shielding to insulate a troubled area from heat. Even if the actual heat is not lessened, shielding could possibly eliminate a shut down.

green hornet, are you implying you know have a newer model with minor changes based on the serial number?
 
that is very informative...so if the lite comes on we should hold off shooting and wait for the camera to cool and the warning to go away.....thanks for the info
