Sigma 67mm WR Circular Polarizer Filter

B&C Camera

The Sigma 67mm WR 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. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of
