Next large sensor camera to have this Feature would be a best seller

The problem is that it introduces polarization into the image at all times, and it also is never fully clear so you are always cutting a significant amount of sensitivity.
 
No thank you for the clickbait-style thread title and zero-explanation link, to a video that could have just been an article I could skim in five seconds.
 
According to the video, it goes from 1/4 to 1/128, so I assume there's a separate setting to take it out of the optical path altogether when you want full transmission. The issue of polarization is a real concern, though.

What I really want to know is how they got those three owls to pose for the DOF demonstration.

Well it doesnt use any polarizers. It uses lcd panels in front of the sensors that increases density. How it affects the final image, i dont know but it sure is a great direction for future cameras.

its like an nd wheel on eng cameras where u can rotate out to 0 ND.

The topic header got chopped off sorry about that it looks click baity.

Aren't LCD panels polarized? ; )
 
LCD panels are in fact polarized, and yes there are polarization issues with such an implementation.

I have been involved with R&D work on the use of such technology in 3D camera systems, in camera accessories, in projection systems and in remote light fixture dimming. Polarization is absolutely an issue, as is the fact that at it's clearest such an LCD panel will still restrict a significant amount of light.
 
I see. pretty cool to learn this :)
is there a similar tech that does not polarize?
