The Rotating 100mm Circular Polarizing Filter from Kase fits most 100mm-wide filter holders that accept 2mm-thick filters. Made of multicoated Schott B270 superwhite optical glass, this filter can be easily rotated into proper position using the thumbwheel at the top.
A circular polarizer filters rotates to organize light into more directional rays, reducing the glare of reflective surfaces and darkening blue skies for improved outdoor photography.
