strange...but I don't buy it either. i shoot and have been known to flare a little here and there...checked my cameras and no sign of this what so ever. but maybe it's because I live up North where we are farther away from the equator
anyway i think something else may be causing the burns.
oh well..flare away, it's just a tool and eventually tools need replaced.
I BELIEVE I HAVE AN ANSWER (kinda long but chill, it is worth a read). I picked up an EOS 1-v from a sports shooter a while back and he showed me a similar burn on a body that he had started to tear apart (1dMIII). After much speculation and a trip to CPS, the question was asked if his cameras were ever set down in direct sunlight for any period of time over 30 seconds. His answer was, "of course, I carry 3 bodies to cover sports and usually two are on the ground or a laying on a bag near me." The techs said that the camera/lens being in the same position to the sun for quite some time led to the burns/melts. He said it can happen inside or outside, it just has to be the perfect storm of angle of sun and lens.
I'm not saying that shooting into the sun is not the culprit here and I'm definitely not saying that I won't be shooting into the sun anymore. What I am saying is that anytime I set a camera/lens down where there is sunlight, I make sure to cover up the lens with something (you know, like a lens cap!). So that's my story and I hope you enjoyed it. Happy 50L flare to all and keep up the awesome!
Think of the sun intensity off the sensor but in the image circle. Look at where the burn is. For your flares the sun is at the edge of the image, but much brighter sun goes in the camera.
damn... i just checked my sensor on the 5D2 and no burns thanks goodness, could it possibly be a manufacturing defect when they cast the plastic and laser cut the die out?

That wouldn't explain the sensor problems, just the melted plastic.

Hey just letting you know, that my 5D original has those marks.
The shithead who sold me the camera on this board failed to disclose it. I wanted to leave him bad feedback but didn't want a negative on a $1300 purchase.
I posted the pictures asking what they were, people suspected burn. I e-mailed him and he said since I shot it and it works to go shove off. A guy I'd like to smack right in the head with the camera if I seen him. This just confirms what the jerk did.

I'm joining this thread a little late... but there are a couple things that I don't follow....
(1) in the original photo, the mirror is down, and the damage appears to be to the mirror box - not the sensor (not that you can see the sensor in the shots provided).
(2) in all the example shots you provided, I would have thought that the exposure time would be rather short. I can't see how sensor damage is going to result from the shots that were provided (flare or not).
(3) the exception of course would be if you were using Live View, as the mirror is up the whole time. If I recall correctly, the manual warns about shooting directly into the sun in Live View in more than one place.
I am very curious to hear what Canon has to say. From the appearance on the damage, it would seem like the part that melted should be made of metal, not plastic...
Okay, so I'm quite new to this forum but very much enjoy the insight I find provided here. That said, I wanted to post this thought as I don't think it's been addressed yet. I believe Sam that you said Quan's camera had the same or similar marks. Is his also exibiting the same tendency to overexpose? Someone else also mentioned having them on a used unit they had picked up. I guess my thinking is that even though you've incurred this damage, is it possible that it has nothing to do with the problem you're having with the camera? Perhaps something totatlly unrelated? Just a thought...hopefully Canon takes care of you either way....
From Canon manuals:
1DMkII (no live view option) -
"Do not leave a lens or lens-attached camera under the sun without the lens cap attached. Otherwise, the lens may concentrate the sun's rays and start a fire."
5DMkII - the exact same caution as above appears.
That's why Canon doesn't have a dedicated MLU button - they're afraid you'll accidentally lock up the mirror when you put your camera lens-up on the ground, and start a focusing screen fire, or even worse, a grass fire.
Actually, I could see live view operation causing sensor burn if pointed at the sun for a while.
