The MIR-20 20mm, produced in the Soviet era from the 1960s through the 1980s, is a rare and highly sought-after wide-angle lens, celebrated for its unique character and cinematic look.
With an aperture of F3.5, it’s not the fastest lens in the set, but given its ultra-wide field of view, most of the frame remains in focus naturally, making the slower aperture less of a limitation. The minimum focusing distance of just 0.18m allows for impressive close-up shots, making it versatile for capturing dramatic perspectives.
One thing to note is that the large front element captures light from all directions, leading to significant flaring and a lower contrast look. The lens is sharp in the center but softer toward the edges, even when stopped down to F8, making it less ideal for edge-to-edge precision. Despite these quirks, the MIR-20M is a favorite among Soviet lenses for its unique look and creative potential.
