Formatt Hitech 85mm "P" Series Circular Polarizer Filter

The Hitech 85mm circular polarizer filter produces the same effect as a linear polarizer filter, but is used in cameras where polarizing elements are used in the beam-splitters of the camera. Circular polarizers is made from a different polarizing material than linear and will usually prevent the cross polarization. The circular polarizers may only be used one way in front of the lens and are marked accordingly.
