Dots on the footage

I appreciate this thread as a caution against lasers. I personally put fixed cameras next to DJ aiming away from lights, thereby avoiding most extraneous light, but when I'm wandering around handheld I will be extra careful.

Wow, thanks for this thread guys. Now I won't film anything with lasers with my X70 or my a6000. :(

Found this info on the polarization of laser light:

Maybe someone could come out with a set of specialized polarizer filters to filter out laser light, and they could be marked by the type of laser they filter, so people who need to film these shows could protect their cameras as much as possible?

EDIT: Would only really work if the laser light coming "directly" into the camera is attenuated but from the side, reflected off a mountainside or smoke in the sky, etc. is not.

Thanks all, yes its a good lesson for all, and expensive one for me, as the repair cost is going to be the same cost for the Job, what shits me is your right, the Laser guy said to me, you be right they are pointing up a bit, not at the camera, I didn't realise just how quick it can happen. I will get a screen shot from the footage and post it tomorrow.

OMG that sucks Robert! :(

I saw the exact same red dots on a Canon DSLR forum, a guy rented out his 5D and got it back with those!

I thought the days of tube camera burn in were long gone.
