How to break your 5D Mark II in a split second

Considering all we use a 5DMKII for is video, this is pretty scary. Fixable do you think, or would it need an entire sensor replacement?

Well, if the issue is sensor burn then I'd expect it to be a sensor replacement job, it is a little bit scary though...

Thanks for reminding me about this. Think I'm gonna carve a warning in the back of my 7D, just to be on the safe side!

Thats quite easily shagged isn't it! I was playing with a laser pen on long exposure not so long ago!!!

The lens focuses the laser on the sensor so will break it for sure.
Collimated beams without the lense are fine if power levels are not silly.

Ouch! Strange in the second video though that as the camera moved and the laser moved back again it didn't create more damage? I would've expected to see multiple "lines" across the sensor from each time the laser sweeped across? :confused:

Expensive mistake :/

Ouch! Do you think insurance would cover that?

Sod that. Send it back under warranty unless the manual explicitly states don't shoot video near laser light shows.

I'm pretty sure I would just say. Errr whats this? Fix please!

If you freeze frame, then you will see that in the sweep that caused the problem, the laser is exactly in the middle of the frame pointing directly at the camera. It looks to me that you can get away with an angled strike, but directly on is the problem.

I am surprised by that, Its just that the energy of these lasers is extremely low as they need to be eye safe so we are talking sub milliwatt levels and its streaked in space as well. I really dont' think the sensor is that sensitive. If you can image focusing sunlight is much much higher power levels on the sensor.

Im sure ive seen (not literally) Lasers from 250mW easily up to ~8W in shows? I think that would do it

Lucky I don't shoot video on my 5Diis.

I saw a you've been framed style show the other day where a wedding photographer is walking backwards shooting down the aisle, until he trips and falls backwards with 2 cameras into a pool.
Took out a lot of expensive equipment in one foul swoop.

It will only do this is your using live view or video. If your shooting stills this will simply burn your eyes (unless your lucky enough to have the shutter open during the passing of the beam, then it will do exactly the same thing as it did with the video, but at least it spares your eyes...)

I doubt much (if any) of that stuff died... perhaps the one that got submerged for a few seconds might've died, but I doubt the lenses died, the other camera only spashed in so that'll certainly live.

If I had a 5D2 and this happened, I would cry.

...Hmmm warn the cameraman that he's heading for a bath? or just carry on filming hoping for some 'wet' footage
