Photography with this filter takes on a new dimension. The clouds appear more distinct and the colors more vivid

Personally, I give it 5 stars because it is a good filter. Of course, it didn't do the job I wanted, but that's my own fault

It fits perfectly with the lens, the build quality for its price is excellent and I had no complaints, for more amateur use it is just what you need

The only negative about this ring is that when you put it on and want to take it off, it is very tight and difficult to remove.

The filter was placed on a 50-250mm lens on a Z50, and when you try to focus above 150, it creates a problem with focusing. Basically, it doesn't focus correctly, and even manually you can't find the point at all. I don't know if mine is defective or crooked, but it doesn't work at all. The polarization, on the other hand, is fine, but what good is that?

The construction of it is very good. It does its job as a polarizer equally well. It eliminates most of the light reflections on glossy surfaces, which really impressed me when I first tried it, as I did not expect it to make such a difference. At this price, I don't think there is any competition.

Fantastic tool, it has helped me a lot with reflections in indoor spaces.
- Attention* it does not work in every case, I would say it is 70-80% dependent on the direction of light.
- The only negative thing I would say is the unscrewing, it is quite delicate and I would recommend not tightening it too much.

Very good result in use, but very hard adjustment ring for polarization. Maybe it will soften over time. For now, 4 stars

Excellent product. The photos come out much better. Definitely worth its money. I highly recommend it.
