If reflections and glaring hot spots are the bane of your existence, here’s something to make life a little easier.


This NiSi 4 x 5.65" Enhanced Rotating Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.


Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.


Constructed from optical glass, this filter is mounted within a 7mm thick, 4 x 5.65" aluminum alloy filter tray for use in matte boxes that can accommodate ARRI R2 filter rings. In order to adjust the intensity of the polarization effect, an external dial on the filter tray allows for the independent rotation of the circular polarizer. Each glass surface includes one layer of nano coating, which results in an improved beading effect when in contact with water or oil for greater cleaning efficiency.
