Olympus's ultra-fast OM prime — 55mm f/1.2, the fastest Zuiko normal lens ever made.
The Olympus Zuiko Auto-S 55mm f/1.2 is a fast standard prime from the Olympus OM system — one of the fastest standard primes available for any 35mm SLR system. f/1.2 maximum aperture at 55mm is an extraordinary combination. Highly prized for adapted mirrorless use. Olympus OM mount.
f/1.2 maximum aperture. 55mm focal length (full-frame). Zuiko Auto-S optical formula (7 elements in 6 groups). Manual focus. At approximately 350g. 55mm filter thread. Olympus OM mount.
f/1.2 at 55mm is among the fastest standard prime combinations available for any 35mm SLR system — producing very shallow depth of field at standard focal lengths. Highly prized for adapted use on Sony FE and other full-frame mirrorless systems for its distinctive wide-aperture rendering. A sought-after lens with collector and user appeal.
On the used market the Olympus Zuiko 55mm f/1.2 is a rare and valuable fast standard prime. Condition checks: 55mm front element for marks, aperture blade condition (oil-on-blades common and particularly delicate at f/1.2), focus ring damping. Olympus OM mount — requires OM-to-mirrorless adapter. Rare — verify authenticity.
