Bests & Worsts Reviews from Amazon

This CPL is way better than than the asking price. I normally tried to avoid using filter as much as possible because of added time and complexity. Polarizer is the only filter that I carry. I normally gravitate towards better brands such as B+W and Hoya if I have to buy. This AmazonBasics CPL is so cheap that I have to get one just to test it out. It is very well constructed. The coating is visually flawless. Rotating the polarizer is smooth. So far so good. I tested it for removing unwanted reflection and compared it to a B+W multicoated and a Hoya uncoated. I could not tell the difference between this AmazonBasics and the B+W. Visually, not much difference in the end result when compared to the Hoya. However, shutter speed was faster for the same end result, meaning the AmazonBasics transmitted more light which was the result of better coating. This is very good initial result for something that cost almost next to nothing for a multi-coated CPL. I am still testing it and will update with more results. The pictures attached are comparison of 1) no CPL filter, 2) AmazonBasics CPL filter, 3) top brand name CPL filter. It is quite clear that the AmazonBasics CPL filter performed equally well as the brand name CPL filter.
