    Overview

    The Mir-20 20mm f/3.5 is a Soviet-era ultra-wide lens with solid build quality and smooth mechanics. Optically, it offers good central sharpness when stopped down to f/8-f/11, but edges are soft and chromatic aberration and vignetting are present. Its unique 0.18m minimum focus distance enables creative close-up compositions. Multicoating controls flare well. It suits photographers seeking a characterful, manual wide-angle lens for deliberate shooting, though it requires post-processing for fringing and is not an everyday carry.
