Excellent. I use it on my Sigma 150-600 telephoto lens and it works perfectly. You can't see anything in the image and it feels like excellent quality.

Works great couldn't notice any deterioration in image quality. I Shot professionally, I use it for my fujinon 100-400mm and my fujinon 16-55 f2.8

Just received today. It feels light-weighted, even a bit flimsy, when I hold it in hand. Yet it feels reasonably good quality. Compared to the B+W filters I have, it seems to have a thinner glass substrate. Given the 95mm size I even feel that the glass could warp under stress although I know this is unlikely. I curious am about its optical performance. Price wise this is unbeatable which is all other UV filters should be priced at. There is simply no justification to see a UV at $200 or even $300. Selling a UV at $200-300 sounds to me like people want the money but don't want to work reasonably hard.
