Total damage, fried. Think that a laser can perforate a paper, so I'm not surprised can kill pixels on a sensor....

Interesting, that there is not even a single word about it in any Canon's SLR manual. There is about exposing to heat, leaving in a car, observing the correct battery charging, sun etc but nothing about laser projectors. I don't think it's well broadcasted information. Interesting again, if Canon honors warranty in case of such a damage?

Totally depends on the wavelength of the laser, the amplitude, and the phase.  I've seen 800nm wavelength lasers sear through paper but 400nm do nothing but reflect, because the amplitude and power (wattage) weren't there.  Again, it totally depends.  Some lasers bounce off paper while others cut through metal.  One common misconception is that a laser is something special, when it is nothing but light, that we see everyday.  The ONLY difference is that the waves or photos are all in-phase, vs. random phase by normal light.  You can have radio wave lasers, light wave lasers, X-ray lasers, etc.  It's an electro-magnetic field like any other.

I'm guesing the problem with the sensor is too much of one thing, it cannot be handled.

AAPhotog:
This has been known about for quite sometime. I believe it has to be in liveview as well when the laser hits it.

Im just curious how canon would handle a warranty repair on such instance as there is certainly no warnings from them about the possibility of this happening. So would it be user area and no free fix/replacement from canon?
