Overheating Warning Icon in mild temperatures

Hey, Randy--any chance of going outdoors in more heat and trying it out?

So what has become of this issue? Canon has had time to come forward and make a statement one way or another. It's obviously internal heating and not ambient. it's seems like it's more from 60fps and having two processors work harder that can heat up. Maybe the temp sensor is set too low. Maybe the batteries are also working harder that adds heat. The 3" LCD can add heat, but the 5DM2 does not do this. The camera sensor also adds heat, but it's smaller than the FF 5DM2.

I am holding off buying and recommending this camera until something is officially announced. I think Canon should be talking about this. Please, don't post excuses on Canon's behalf. I have heard them all and we still don't have any answers.

Reading through the thread, it's 90% speculation, and three people with specific issues, which primarily seem to center around 720p and 480p. Have these people actually contacted Canon? Charles said his dealer might be replacing his unit, but nothing more has been said. What makes you think Canon is even aware there is an issue at this point?

Canon has *already* made a statement. It's found on page 159 of the owner's manual.

This thread is for feedback from people who are using the camera to post about their real-world experiences with the overheating issue. There is very little worthwhile input that can be offered by someone who doesn't actually have the camera in hand. The next posts to follow here will come from members who have technical feedback to contribute regarding the temperature issue, based on actually testing and using the 7D. I'll warmly welcome an email from any one of those folks, which will quickly re-open this thread and put it back on track.

Mine is currently on loan to a filmmaker in Austin. I've asked him to report any overheat warnings, but he's shooting 1080p24 mostly indoors and therefore is not likely to run into it. But I'll find out on Monday if he did.

Received word from the person who borrowed my 7D for a film shoot in Austin -- he never saw the warning through several days of filming, at 1080p24. He didn't use any other frame rates.
