12mm · f/2.2
The Mir-11 12.5mm f/2.2 is a compact cine-style lens originally for 16mm film, covering S16 sensors with slight vignetting. It is soft wide open with blooming highlights, improving by f/2.8 and sharp at f/4. Build includes a stepless aperture ring and 270° focus throw, though stiffness may vary. Best suited for users seeking a vintage, dreamy look on MFT cameras with crop mode, but not for critical sharpness at maximum aperture.
