Olympus Zuiko 50mm f/1.8 Auto-S - Olympus OM Mount

The Zuiko 50mm f/1.8 Auto-S was the standard prime lens for the Olympus OM system for many years. Renowned for its exceptionally small size and lightweight construction, it offers a bright f/1.8 aperture and sharp rendering. It is a versatile choice for everyday photography, street work, and low-light shooting, balancing performance with the OM system's compact philosophy. Used examples should be checked for internal dust and the presence of fungus, particularly in older 'silver nose' versions. Later 'Made in Japan' versions are often preferred for their updated coatings. SDS inspects the aperture ring for distinct clicks and ensures the focusing helicoid moves smoothly across the entire range without grit or dry spots.
