Hoya NXT Circular Polarizer CPL CRPL High-Transparency Optical Slim Frame Glass Filter (40.5mm)

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.

Not too bulky, smooth turning, easy to get on and off the camera lens.

This is a good, intermediate polarizing filter. Cheaper models are available, but much more expensive are also available. Good middle-of-the-road compromise.

It's very well made and performs perfectly as you would expect from a Hoya product.

Helped reduce water glare. Good value for the money. Also saved my lens from getting a scratch.

I use these filters for a Nikon AW100, which allows filters to be added on the front via the special attachment. Since much of what is shot with this camera is water and fishing scenes, circular polarizing filters are a great tool for looking into clear water. I like the NXT, but it is hard to find. It gives good quality images and color without the flatness that can accompany polarizing filters. The seller of the filters timely provided what was advertised and in good condition.

Nice sturdy filter. Turning the rim to find your desired polarization is smooth and will stay where you place it with no problems. Pictures come out great, very vibrant and clear and no vignetting on my EFS 18-55mm Canon len.

The inner ring that attached to the lens is a bit thin but it probably needs to be not to intrude on the wide angle lens. Otherwise a good filter and works well.
