82mm C-PL (Circular Polarizer) Multicoated Multithreaded Glass Filter — Rugged Black Metal Ring for Sony Alpha Alpha NEX-3

Precision 82mm C-PL circular polarizer with multicoated, heat treated glass — ideal for both video and photography. Light transmission reduces between 2.3 and 2.8 (approx. +1.3 stops). Housed in a rugged metal filter ring with a black finish, the slim profile is engineered to minimize vignetting. The multithreaded construction allows attachment to lenses and stacking of additional filters on top.
