Canon 7D overheating under normal conditions?

So I shot some footage under normal conditions, probably about 75 to 78 degrees under 3 lowell lights and I get the overheating symbol on the LCD for the first time... The shoot lasted about 3 hours... I'm shooting 1080 24p footage on a Lexar 16gb UDMA card... Is that normal??? I know some users can shoot the entire day on 1080 24p and have nothing come up... Are some units (including mine) just defective?

Any help would be appreciated...
 
I don't think I would call it defective par say, but do some cameras have the ability to withstand high temps, run times, stresses, ect. The simple answer is, who knows. I don't think in your cAse though that it was a matter of heat in the air. I would have to say that it was more or less the heat in the body. You stated that the shoot was 3 hours of continuos shooting. That means your proscessors where running all that time. And remember, we have 2. That equates to twice the heat and do to the new weather sealing many of us have come to the conclusion that our cam has a respritory disease. On shoots that long it is nescesary to give your workhorse a break. Either that or aid in it's heat issue ie. Coldpack.
 
I agree with Perry...
dude, keep the air moving...I shot 2 x 17 hour days back to back in a green screen studio with lights galore and not one issue. I shot in 4 hour increments, with a 20 min break for CF offloads....The cam was barely warm to the touch throughout the entire process. Cold packs are nice to have on hand for sure, but I never once needed to pull mine out of the freezer. And for me...fans are a must to have on hand blowing around air during setups.
 
Azboy, I've only had my 7d overheat once and it was when I had a 650 placed directly beside the camera. After that shoot I found that by setting my camera to automatically turn off every two mins if not touched, then my camera would not overheat. So if you leave your camera to go and tweak lights most of the time it shuts off allowing the camera to cool. Since making this change it hasn't overheated since.
 
hornet, was there a certain issue of 7d's that were faulty? i know i had one of the first batches in the states and i will get issues sometimes where it will just over heat real quickly but then be fine for a while. but also, i'm not shooting udma cards(i know, i know. ordering them soon!).

Were you holding the camera most of the time? Or was it on sticks?

This is important as well, for overheating and conserving battery power both. Someone had my camera switched to 30 minutes and I didn't realize it, went to pick the camera up and it was blazing hot.

Definite no no. It takes a few seconds to activate Live View, not worth a few minutes of downtime or the camera shutting off in the middle of a take due to overheating.

I agree 100% here. Having the camera shut off after 2 minutes is probably the main fix to the 7D overheating issue..which is a total non issue for those of us who shoot takes.
 
First... Thanks for the responses guys, I really appreciate it!

The camera was on a handheld spiderbrace... My shutoff time is set at 8 minutes... prlly should set it to 3 or 4...

As for the shooting, it was probably 8 minutes or less in between takes and as I said, the shoot was for about 3 hours.

I'll look at my serial number again and post it on here, I did get the camera as soon as it came out... And I am running the latest firmware.

I can not say that I know this for a fact.

What I do know is that Canon constantly makes improvements that they never disclose. Some early cameras were said to focus in front or in the rear of the subject. That seems to be quietly resolved in cameras serial numbers 04 and higher.

The over heating issue doesn't seem to happen to ALL cameras, so maybe that has been addressed.

I do not know. The current release is at 06 (serial number).

Of the people I have hear complaining about overheating, it seems they are all below 04 (first 2 digits of serial numbers).

Some are worried about providing their serial numbers, but no one can do anything with that (except for registering it, and if it is already registered, they can't do that) I say Relax to that.
 
Green Hornet, could you post an example serial and what numbers you need to look for to see the "current release"? I haven't looked at a 7D serial before, that's why I ask.

Edit: I googled a serial "0220105786" Are the first two digits the numbers you're referring to?

The first 2 digits... in the example above, that would be a very early release (02)

The rest of the serial,
I have not seen that type of serial.
Unless it is from a kit
