The NiSi Cinema 4 x 5.65" True Color Rotating PL Linear Polarizing Filter is designed to reduce reflections and glare in the process of filtering out light that has become polarized due to reflections created from non-metallic surfaces.

A polarizing filter arranges and filters this directionally polarized light perpendicularly to the reflected light, allowing for much of this light absorption. This process creates a noticeable reduction of glare and reflections from non-metallic surfaces as well as creating an increase in the saturation of skies and foliage.

The NiSi Cinema 4 x 5.65" True Color Rotating PL Linear Polarizing Filter is 6mm thick and fits into a 4 x 5.65" matte box tray. Featuring an M0.8 focus control gear for adjustments to be made manually. It also includes a 1/4"-20 thread which allows a magic arm to be used with the unit. You will also find a 15mm support rod as well as a padded storage pouch.
