Olympus's fast ultra-wide for OM — 21mm f/2 Zuiko, one of the fastest ultra-wides of its era.
The Olympus OM 21mm f/2 is one of the fastest ultra-wide primes of the film era — f/2 at 21mm was extraordinary when most alternatives were f/2.8 or slower. Part of the acclaimed Olympus OM Zuiko lens system.
Optically good — sharp from f/4 with the fast f/2 providing more light and shallower DOF than typical f/2.8 or f/3.5 ultra-wides. Zuiko quality. The f/2 was a remarkable engineering achievement at 21mm.
Olympus OM mount with 49mm filter thread. Compact — the OM system's miniaturisation philosophy. Manual focus. Metal construction. The fastest 21mm available for OM-mount cameras.
Available used at professional to luxury prices — the fast f/2 at 21mm is rare and commands premium pricing. Adapts to mirrorless cameras via OM-mount adapters. For OM system collectors and adapted mirrorless ultra-wide enthusiasts.
