The packaging of the polarization filter already gives the impression of a higher quality product. The filter is housed in a well-made and elegant bag made of synthetic material and leather with a magnetic closure. This offers good protection against scratches. However, there is no reinforcement against point loads or bending. A loop makes it easier to remove the filter.

The filter is very well made, which shows on the one hand on the filter thread and on the other hand on the glass. Due to the precise manufacture, the filter can be screwed onto the lens very well and without snagging or tilting, as is often the case with inexpensive filters. The glass shows no distortion or distortion whatsoever.

The filter is a bit difficult to turn, but defined and even - best described as viscous resistance. Thanks to the non-slip ribbing of the filter, twisting is still possible. Here you just have to be careful not to loosen the filter, which is why I deduct a star. I rotated the filter frequently for the test to overcome any initial wear and to make the rotation smoother. However, this is always only a short-term effect.

Photographically, the polarizing filter does what it is supposed to do. There are enough blogs here for a holistic overview, … . In my opinion, at least in the field of landscape photography, the most important filter. Therefore, I would recommend buying a good filter here. Especially now in autumn the colors of the wet forests really come into their own.
I could not find any negative impact on the image quality on my Nikon D850 and Nikkor 24-70mm F2.8 lens. So full points in terms of image quality.
