received the polarizing filter for free as part of the Vine program to test. Since mine from another manufacturer is already getting on in years and does not fit my most used lens, I was happy about it. Even the packaging is very high quality and the supplied bag is very well thought out and easy to handle. You can even make a pretty frame out of the packaging. A microfiber cloth for cleaning is also included. The filter does a good job removing annoying reflections and enhancing the colors in the image (green from the grass, blue from the sky and also white against a blue sky). For this reason, the filter is great for landscape photography. Naturally, the polarization filter reduces the light by up to several f-stops. However, this must generally be taken into account when using such filters. However, this is not a problem, especially when taking landscape photos with a tripod. The filter was inexplicably stuck (couldn't find any handling error or wedging) on the lens when first used. That's why I only gave it two stars in the rating. He also does not use force to remove. It could only be removed again using a special tool from a third-party provider. After that I changed the rating to 5 stars. Because the filter lost some color on the frame when I tried it without special tools, but it held up great and still worked great. Now and then I can't get it off when using it. But after I screwed something on the adjustment ring for the polarizing filter, it then came off again. Just not without problems. That's why I'm correcting my rating again! 4 stars this time. It's still a mystery to me why this works. You can hardly grab it because the back ring is so narrow that you can't grab it with your bare hands. In my opinion a design flaw! This high-quality filter offers good value for money.
