If I ever get the Hoya 77mm UV filter off the front of my 80-200 f/2.8, I will gladly send it to you. When I got my Nikkor 300mm f/2.8 it was fitted with a 127mm? Hoya UV filter which had to be destroyed to open up the lens. I was sad about that, they are VERY expensive. I suspect the one on my 80-200 will have to be destroyed to get it off, maybe there is some trick to get it off but the Nikon service guy's tried and gave up.

I have numerous images I took in tests which disagree totally with arguments for them. They are to be found in an early post on this forum, the loss of contrast is dramatic, removal of the filters completely restored the expected contrast. I will try to find them on my system. It's most pronounced when there is back or side lighting.

As for UV contamination, very few lenses pass UV in any great amount and the IR/UV filter permanently fitted to the sensor limits the admission of Infra Red and Ultra Violet light which can reach the sensor.

If you feel the UV filters improve your photography that's fine, we all have different perspectives.
