Ultra Slim Ring
77mm NiSi HUC C-PL PRO Nano circular polarising filter. Polarises light entering the camera reducing reflections on water and in glass. Polariser is able to rotate for desired alignment. The Nano coating rejects water and oil making the filter very easy to clean. The HUC range is the best filter Nisi make, with both sides of the optical glass coated to prevent scratching and dirt. Fits any 77mm lens with a filter thread. Ultra Thin frame makes it perfect for even wide angle lenses.
