The NX Circular Polarizer is the only polarizer that will work with your NX Series system. It snaps into place, hides within the body of the frame, and is controlled with a dedicated wheel on the side of the holder. The unique design allows you to stack up to two more square filters in front without vignetting. The filter is manufactured with Schott B270 glass and uses a high-transparency polarizing film that blocks only one stop of light. It includes anti-reflective multi-coatings and a hardened topcoat that is scratch and oil resistant for easy cleaning. Filter includes its own protective carrying pouch
