Haida Optical Circular Polarizer Filter Review

Tested several times and I am very satisfied with the colors they produce, it really gives a polarizing effect without artificial shades. Costs money!

Very good filter. Very clean with no visible deterioration in image quality. I have a lot on mine and will be using this filter for many of my professional jobs.

glass filter and metal housing - good quality. You know the BIGGEST boys in 4 inch filters, this baby fits! (Half price.) Please note the thickness of 2mm. Some non-brand filters are 3mm thick and will not work if your holder is designed for 2mm. I haven't tested it yet, so who knows - I can tell they somehow messed up creating the CPL, but I highly doubt it. If I find that the filter doesn't remove glare or enhance colors like all CPS do, I'll update this review.
