Sirui 77mm Nano MC Circular Polarizer Filter, Aluminum Ring

This is great bang for the buck. Good quality glass and coatings, and the slim profile is nice for wide lenses. The ring is aluminum, so it's not quite as durable as a brass B+W. I'm more careful with the threads on this filter than the ones on my B+W polarizer because it takes some fiddling to get the Sirui threads lined up properly. I've used cheap filters in the past and while the threads on this one are better, they're not premium quality. That said, the optics of this filter are great and I enjoy using it. It's ~1/3 of a stop brighter than my B+W MRC polarizer which is an advantage in lower light. I love the slim design, which doesn't cause vignetting on my ultrawide full-frame lenses. If you're careful with your gear and don't mind taking a little extra time to make sure the threads are aligned when you're mounting the filter on your lens, this is an excellent filter. If you're expecting the build quality of B+W or Hoya, it's worth the extra money for those brands.
