This filter performs as expected. I put it on my Nikon D40 telephoto lens to protect it and it does. Price was good and not made in China.

I've been looking to upgrade the UV filter on my telephoto lens and this looked like a great option. The glass is very clear, and it doesn't cause any issues or artifacts with my photos. It is a really nice UV filter for $20 (at the time of this review), and the quality and materials seem really great especially for the price. I would recommend this!

The NEEWER 58mm Lens Filter Kit Compatible with GoPro Hero 8 7 6 5 is a very fine set that includes all the filters, adapters, and caps you'll ever need for that 58 mm lens. I tested the circular polarizer and each of the neutral density filters on a Sony A7RIV with a 45mm Samyang lens with a 58mm filter ring adapter. The nearby photo with the with the brightly lit barn was shot with the polarizer and an UV filter. As you can see, no vignetting whatsoever. The barns in shade photo was taken with an UV filter, the polarizer, and a ND32 filter. Again, no vignetting. I had the same results with the other ND filters. These filters will not adversely affect your shots. It's a great $49.99 kit and I highly recommend it.

This is an amazing deal. Not just for the Polarizer or ND Filter. The TWO Lens Hoods are well worth it also, plus 2 carrying cases pluslens cover and cord/plastic attachment so as not to lose the lens cover. Regarding the polarizer > it works great. Hopefully my attached image ofcar reflections makes it in here. It also takes the shine off leaves, if you turn the polarizer dial. I tried other filters at camera store costing over 120$ and don't see any differences. For the price and number of items and lens protection this is well worth it.

This filter works great. I have used this filter on a Nikon 18-70mm lens and have produced excellent pictures. I have yet to experience any flare with this polarizer. Great polarizer for a great price.

It's my first telephoto lens, but the results look great.

I had previously purchased a cheap circular polarizer filter and I could not get my lens to focus properly with it on. So I spent a little more on this filter and I am very pleased with the results! It worked great and has fine clarity. I'm looking forward to creating much better landscapes with this filter.

I needed a polarizing filter for my ultra-wide angle lens, and after a bit of research, I learned that it was very hard to avoid vignetting at the widest angles, and that a high quality slim filter might reduce, but perhaps not eliminate the problem. I decided to take a chance on the Hoya filter. Glad I did. Paired to a Canon 10-18mm lens there is no vignetting, even at 10mm. Because the filter is so thin, some care is required with installing the filter so as not to damage the threads. The Canon lens cap does attach to the Hoya polarizer without a problem. Finally, the optical quality is excellent. I see no signs of distortion or chromatic aberration. In addition, I don't get the dark banding from the polarizer across the sky that some less expensive polarizers produce. The color deepening effect is even and pleasant, The operation of the rotating bezel is smooth, and the bezel holds the position it is turned to.
