Re: Can the laser show my local bar band uses damage my Canon 5d3 sensor? Any new data?

I am going to repeat this just because I know the potential for irreversible eye damage.

"It is not something to mess with as it can happen very quickly and the individual not even realize it until too late."

When you are getting defused laser light, it is not readily apparent.

[ Edited ]

The thing is nobody stupid enough to try it after 08. Maybe someday the guys from DigitalRev will test it but I don't want to test on mine for sure.

I don't know the cost, but the 5DMII sensor (party only) is selling around $1000. I think the 5DM3 will cost more and labor + Canon mark up, it will cost around the price of Refurbished 5DM3 roughly $2500. Just my guess, but I think it will be around that price.

Wow--those videos are pretty **bleep** convincing.  Thanks for the link, and for the info. I think I've shot my last laser show. . .and I'm glad I just got lucky and didn't destroy my camera's sensors.

Thanks for the price info, hsbn.  That'll be useful when the band insists it's perfectly safe.  As for nobody being stupid enough to try it since '08. . .well, here's one guy who was!  Although I'd like to think it was more ignorance and even naivity; I never gave a thought that a public show like that could be dangerous to the audience or to cameras.  Live and learn.

No, I actually mean "radiation".  Industrial lasers can be so powerful that even the defused radition from a reflective surface can be hazardous to the eye. It is not something to mess with as it can happen very quickly and the individual not even realize it until too late. There is no such thing as a perfect laser beam. Now you may want to not believe me, you can go with what you belive to be so.  You are certainly free to take the chance. The choice is yours.

A little studying up on lasers may change your mind.


I guess I still don’t understand what you mean by “radiation”; it sounds like you’re talking about scattering or just a reflected laser. Do you have any literature you can point me to?  I would love to do a little ‘studying up’. I admit that I’m no expert with lasers, but I have done a bit of work with YAG, argon, xenon, and little HeNe lasers.  I don’t know of any other kind of radiation from a laser other than its own reflection, which of course is just more electromagnetic radiation.  Are you suggesting that lasers can create ionizing radiation of some sort?  Are you manufacturing some sort of Death Ray, eBiggs?

Are you sure they're using actual lasers? If so, that's pretty irresponsible. But I bet they're not. Most of these indoor "laser" shows are actually high tech light shows using filters, refractors and gobos to xenon lights into patterns. Lasers are only necessary for outdoor shows where the beams need to travel long distances.

If they're using real lasers you should ask them to check if that's actually permitted. They could get into trouble.

Well, the band calls it a laser show.  I checked the website of one of the bigger music supply houses; they sell things called "laser effect" devices but yeah, they contain 10mW lasers (or some other power). So I'm guessing that's what they're using.  Unfortunately.
