The Siri Brass Filters are the equivalent of the Heliopan and B+W brass filters, using Schott glass and numerous layers of MC and Nano coating. In my experience these have been absolutely outstanding filters.

Excellent build quality. Smooth to screw in and out. Very slim design. Perfect resistance of the rotating filter part. Can't beat the price on sale.

Very easy to screw onto the lens. It's smooth. The filter also does its job, cutting down reflections, increasing sky saturation, and increasing contrast. But the filter has a 1 stop ND and color casts a purplish/dark blue color. Got it on sale, so it was definitely worth a try. But not sure about retail price.

I use 58 mm as my largest size filter and use the step down rings to use this really great cpl filter on all my cameras and even my camcorder. The quality in the construction and build of this brass ring filter works on all my 58mm lenses and as I said the step down rings. The thread screws on easily on all my 58mm lenses and the step down rings as well. I highly recommend this filter.

Haven't had a chance to use it yet but it appears to be a quality filter and I'm sure that I'll be pleased with the results when a Circular Polarizer Filter is needed. It appears to stop about one f/stop of light rather than my Zeiss or B+W polarizer filters which stop about one and a half f/stops of light.

Best CPL filter at very very affordable price. Best optical glass with no color or picture distortion at all. I was so very happy I made the right decision the buy this filter. The filter is very well protected in sturdy case with protective film both front and back of the filter. Best quality filter overall. Sirui is one the best camera gears in the market.

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.

These Sirui Filters are are every bit as good as the B+W for a lot less money. Very Slim Brass Ring makes it possible to use these Polarizer Filters without removing the Sirui Slim UV filters from the lens. First Class Quality of workmanship, highly recommended.

Filters are great. Beautifully made. Easy to grip/ Great specs and the filter case looks like it is made out of aluminum better than any filter case I have ever seen.

This was exactly what I was looking for. I've been using this filter for a couple of years and needed to replace the one I had.
