The NX System Circular Polarizer Filter from Cokin is compatible with the NX Series filter holder. It snaps into place in the body of the filter holder frame, allowing its rotation to be adjusted with a dedicated control wheel in the frame. The filter holder's design allows up to two more square filters to be stacked in front of this polarizer without vignetting when using wide-angle lenses.
The filter is manufactured with SCHOTT B270 glass and uses a high-transparency polarizing film that blocks only one stop of light. It includes antireflective multicoatings and a hardened topcoat that is scratch and oil resistant for easy cleaning.
