C-PL Circular Polarizer — Multicoated 82mm Multithreaded Glass Filter for Pentax K-200D

82mm multicoated C-PL (circular polarizer) made for the Pentax K-200D. Light transmission is reduced between 2.3 and 2.8 (approx. +1.3 stops). Constructed with heat treated optical glass in a slim profile to minimize vignetting, the filter sits in a rugged metal filter ring (black finish). Multithreaded design allows mounting of additional lenses or screw-on filters on top. Engineered for both video and photography use.
