Lasers used in a light show have damaged a Canon EOS 5D Mark
II(
reviews ) CMOS
sensor and I sure didn’t know it was possible, but I thought I’d get a
warning out since it appears to have damaged this guy’s sensor. I would
suspect that all CMOS sensors are probably susceptible – including Nikon,
Sony, Panasonic etc., but maybe because we’re using larger lenses on the
HDSLR cameras would tend to focus more of the laser’s beam on the sensor
(I’m no scientist so I’m just guessing here, but it makes some sense). While
it appears to be mostly safe and not common to get damage (you’ll see in the
video that several lasers hit the camera but only one caused the damage), we
thought you should know.

We thought we’d check up on this a bit and found this page on the
International Display Laser Association’s
sitewhich says:

“Lasers emit concentrated beams of light, which can heat up sensitive
surfaces (like the eye’s retina) and cause damage. Camera sensors are
susceptible to damage, similar to the human eye.

For large scale shows, such as on a televised concert, laser show producers
work with clients to avoid TV camera locations and video projectors (ILDA
Members, see this page for details). However, it is not possible for laser
show producers to be responsible for all cameras and camcorders which might
be at a show.

Therefore, if you attend a show as an audience member, you should take
reasonable precautions not to let a laser beam directly enter your camera
lens.”

So, there you go… you can read more on their site, but I think the idea is
there… be careful out there!
