j_smith6 Posted October 1, 2008 Share Posted October 1, 2008 Wow o.O I use a 40D and sometimes it smells weird too when I change lenses but it has never burned before :) Maybe someone used parts from a older EOS 1D Mark(?) which could be more temperature sensitive? They could still have some parts from other 1D cameras and maybe sometimes they use them when replacing the mirror. I don't know, it's really strange.

mwaks Posted October 1, 2008 Share Posted October 1, 2008 Since this burning event took place after you sent it to Canon for a mirror and software update, perhaps something happened at the Canon shop. In the process of replacing the mirror a component got damaged to cause overheating. I'd send it back to Canon for a possible replacement. Link to comment Share on other sites More sharing options...
sarah_fox Posted October 1, 2008 Share Posted October 1, 2008 Maybe the camera was pointed roughly into the sun, and the focused sunspot made the burn? Link to comment Share on other sites More sharing options...
anthony_zipple Posted October 1, 2008 Share Posted October 1, 2008 Maybe a battery problem overheating circuits? Link to comment Share on other sites More sharing options...

mark soares Posted October 1, 2008 Share Posted October 1, 2008 Hi Ron, Wow, i've never seen that happen and i work in a big camera repair shop. I'd say the most plausible explanation for that damage would be light entering through the viewfinder, and overheating the light baffles in the mirrorbox. It's unlikely that an overheating of the circuits would cause that in that area of the camera but possible in theory. Good luck, Mark Link to comment Share on other sites More sharing options...
photo_dark Posted October 1, 2008 Share Posted October 1, 2008 I had an 1800W gasoline generator light on fire today... kinda scary, but nothing was damaged (outside of the generator). I too question whether or not it was somehow aimed at the sun or something... strange. Link to comment Share on other sites More sharing options...
mwaks Posted October 1, 2008 Share Posted October 1, 2008 Ron.....Tell us if you ever left the camera in the sun without a lens cap. Then we know if we should eliminate the sun magnification theory. Link to comment Share on other sites More sharing options...

ron_s6 Posted October 2, 2008 Author Share Posted October 2, 2008 The camera is always in a camera bag even when left inside the car during a sunny day. Will it be possible that this can happen while I am shooting out there in the sun while the camera is hanging on my shoulder? But it's weird, Canon should know better than making a camera that can cause that to happen. I suspect bad electronic short circuit or something. Sorry, I am not too techy to know these. =) Thanks for all of you who gave insights on this. Link to comment Share on other sites More sharing options...
phule Posted October 2, 2008 Share Posted October 2, 2008 The sun would not do this by random chance. That is a complete red herring. Link to comment Share on other sites More sharing options...
cabbiinc Posted October 2, 2008 Share Posted October 2, 2008 You dont have a high trigger voltage flash on your camera do you? Link to comment Share on other sites More sharing options...
joey_tjosephy Posted October 2, 2008 Share Posted October 2, 2008 I had a 20D and it had a small circular burn hole inside it next to the mirror. I thought it was a manufacture defect. Maybe not? It was like a magnifying glass burn. Link to comment Share on other sites More sharing options...
sarah_fox Posted October 3, 2008 Share Posted October 3, 2008 Ron asked (and we didn't answer): "Will it be possible that this can happen while I am shooting out there in the sun while the camera is hanging on my shoulder?" For this to happen, the camera would have to be relatively motionless, with the sun oriented near the dead bottom of the frame. I don't know how long it would take. It really depends on how fast the lens is. However, I would think it would take at least a good fraction of a minute. To answer your own question, focus the sunlight on a piece of black electrical tape with the lens that would have been mounted on your camera.
