138mm Mounted UltraPol Circular Polarizer Filter 30.5mm and works to attenuate bothThe Tiffen 138mm Mounted UltraPol 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
