Olympus G.Zuiko Auto-S 55mm f/1.2 - Olympus OM Mount

The G.Zuiko Auto-S 55mm f/1.2 is the fastest standard lens produced for the Olympus OM mount. It features a seven-element design that produces a distinct aesthetic at wide apertures, characterized by soft backgrounds and a slight glow. It is highly valued for low-light photography and for achieving a very shallow depth of field on both film and adapted mirrorless bodies. Potential buyers should be aware that early versions of this lens used radioactive thorium glass, which can develop a yellow or amber tint over time. This can usually be cleared with UV light exposure if desired. SDS checks for the typical OM-series issue of oil on the aperture blades, which can cause sticking. We also ensure the manual focus is precise and the rear element is free from scratches, as the glass sits very close to the mount.
