86mm C-PL Circular Polarizer Multicoated Glass Filter — Multithreaded — For Pentax K-r

Multicoated 86mm circular polarizer (C-PL) designed for the Pentax K-r, suitable for both photography and video. Light transmission is reduced between 2.3 and 2.8 (approx. +1.3 stops) to help control reflections and boost color saturation. Constructed with heat-treated glass housed in a rugged metal filter ring with a black finish. Slim profile minimizes vignetting on wide-angle setups, and the multithreaded design lets you screw additional filters or lens accessories on top.
