86mm C-PL Circular Polarizer Filter — Multicoated, Multithreaded for Pentax K7

Reduces light transmission between 2.3 and 2.8 (approx. +1.3 stops). Constructed from heat-treated optical glass and finished with multicoating to cut reflections and boost contrast, this slim filter profile helps minimize vignetting on wide-angle lenses. The robust metal filter ring (black finish) provides durable handling, while the multithreaded design lets you mount additional lenses or filters on top. Optimized for both video and photography applications.
