No heating

No overheating icon at all...maybe I'm just not shooting for long enough yet - judging by some of the posts above I need it going for much longer.

Wow! No way I could fill a 16GB card with non-stop (you know what I mean) shooting. Interested to see what your other tests show.

Canon here is baffled! As I say, I'm on my third and they are all essentially the same. 30 - 40 mins depending on the ambient temp.

This maybe a bit behind the times but I've recently purchased a 7D to use along with my 5D2 and ran into the overheating issue when I used it for the first time on a shoot yesterday.

I was shooting in an air conditioned building, not very hot at all. I was using a marshall HDMI monitor so the LCD wasn't on and used the camera on and off all day. I was shooting at 1080/25 and recording to a 32GB UDMA Sandisk Extreme card. At one point in the day though I was shooting an interview and after around 15 minutes of continuous use the temperature warning light came on. I had no choice but to leave the camera running and the footage looks fine.

It's a bit worrying that this happened in non-extreme temperatures though, I'm planning on using the 7D at an event in St Tropez in May and now I'm a little concerned about this issue.

The 5D was fine all day.
