Zeiss UV are the only ones who do a thorough job.

Yes.
I found an old youtube test back in the day that showed the Zeiss was more effective in its filtering range.
It's the one that's coloured black in theis image because the light from the UV bulb can't actually penetrate it.

Zeiss is better.

One of these is unlike the others.

There are 3.

UV-filters for physical protection, and for converted Infrared cameras (Just be aware only the really good ones like Zeiss is worth anything for UV blocking, pic related).
CPL-Filters for reducing reflections that could block the water surface.
ND-filter for video, to keep a certain shallow aperture, but still reduce the light.

The rest have become obsolete due to post processing.

Holy shit, I just discovered this: https://www.youtube.com/watch?v=OfAwd_8aklE

The Zeiss UV filter was the only one that actually filters UV as advertised.

Canon? Scam
Hoya? Scam
Cheap Chinese trash? Scam.
