I bought two different sizes and both are great quality and well aligned polarizers (the elements that make it at night) this means there are no "cross shadow" (XS) issues. That's a lie! Eventually there will always be an XS, but for me this was just short of the 8th (last) stop when using it on a wide lens (16mm APSC). That means almost the entire range is usable, anything you could ask for with a variable ND filter.

These lens filters look good on my Canon EOS 200D. Contrary to other reviews, they can also be unscrewed again. The front part of the lens is movable, so you can twist the "half face" into the right position. A clear buy recommendation for the price.
