Overview

The Russar MR-2 20mm f/5.6 is a compact, lightweight ultra-wide lens with all-metal construction. Optically, it offers moderate sharpness that improves when stopped down, natural color with a slight warm tint, and relatively low distortion for its era. However, it suffers from softness, heavy vignetting, flare, and cyan corners on digital, making it best suited for film. The lens is not rangefinder-coupled, requiring scale focusing, and its aperture ring lacks clicks. It appeals to photographers seeking a vintage, characterful look rather than technical perfection.
