82mm C-PL (Circular Polarizer) Multicoated Glass Filter — Multithreaded, Slim for Sigma SD15

Designed for the Sigma SD15, this 82mm C-PL (circular polarizer) multicoated glass filter reduces light transmission between 2.3 and 2.8 (approx. +1.3 stops). It uses heat-treated optical glass set in a rugged metal filter ring with a black finish. The slim profile helps minimize vignetting, making it suitable for wide-angle shooting, and the multithreaded design allows mounting lenses or filters on top. Built for both video and photography applications.
