    20mm · f/2.5

    Overview

    The Mir-47 20mm f/2.5 offers decent sharpness and contrast, especially when stopped down, but suffers from coma, distortion, and flare wide open (FotoPete). Its large, triangular build lacks a filter thread and can be awkward to store, though it provides good value for a fast 20mm lens. It suits budget-conscious film photographers seeking a wide-angle, while digital users may treat it as a 28mm equivalent (FotoPete).
