Hoya NXT Plus 52mm 10-Layer HMC Multi-Coated Circular Polarizer Lens Filter, Low-Profile Aluminum Frame

The Hoya NXT Plus Circular Polarizer Filter allows the photographer to remove unwanted reflections from non-metallic surfaces such as water, glass, etc. A circular polarizer is a must-have filter for every photographer and Hoya's NXT Plus is a powerful upgrade to the best-selling NXT series. This filter applies a waterproof top coat to Hoya's polished smooth "clear" glass for maximum sharpness. There are two advantages to having a premium waterproof coating: 1 Water beads-up quickly, and easily slides off the surface of the filter for streak-free shooting. 2 It also makes the filter a lot easier to clean when dirt, water and smudges make their way onto the surface.
