I have tried many different filters (HAMA, Hoya, noname ...), but B + W is still by far the best choice. Although you have to also spend the most money on these filters, but I think the price is always worthwhile. + Residue-free cleaning where other filters often streaks or residue remain + Best fit when screwing + Proposal has no quality loss or blurring in the photos I can recommend everyone this filter. The polarizing filters are TOP!
