Tokina Formatt Hitech 6 x 6.6 Inch Circular Polarizer Filter

Formatt Hitech Polarizers are available in two types of Circular and Linear. Made from high quality Schott glass and manufactured precision bonding and polishing techniques. Circular Polarizers have little noticeable optical downside versus at Linear Polarizer and therefore are recommended for most modern cinematography applications. The Formatt Hitech Circular Polarizer is made from two layers of high quality optical enhancers. The first layer is a standard high efficiency linear polarization foil that will create the usual desirable blue sky and reflection cutting effects that polarizers are known for in cinematography. The second layer is a 1/4 Wave Retarder which spins the light in a corkscrew type pattern to avoid cross polarization on cameras that have 3 CCD design, employ a video tap, or have internal variable ND type effects.
