Olympus Zuiko Auto-Zoom 85-205mm f/5 - Olympus OM Mount

The Olympus Zuiko Auto-Zoom 85-205mm f/5 is a classic telephoto zoom lens for the OM system. It provides a useful focal range for portraiture and general telephoto subjects while maintaining a constant f/5 maximum aperture. The lens uses a one-touch design, where a single ring controls both zoom and focus. It is constructed primarily of metal, reflecting the durable build quality typical of the early Zuiko line. On the used market, the zoom/focus mechanism is the primary area to inspect; it should move smoothly without 'zoom creep' when pointed vertically. SDS checks for the presence of dust or haze within the optical path and ensures the aperture blades are clean and responsive. The front and rear elements should be examined for scratches to the coatings, which can impact contrast.
