Olympus OM-System S-Zuiko Auto-Zoom 100-200mm f/5 - Olympus OM Mount

The Olympus S-Zuiko Auto-Zoom 100-200mm f/5 is a vintage telephoto zoom lens for the OM-mount film system. Part of the 'S' (Standard) range, it was designed to be a more affordable and compact alternative to the professional Zuiko primes. It features a constant f/5 maximum aperture throughout the zoom range and a push-pull zoom mechanism, providing a classic telephoto range suitable for general outdoor photography on OM-series film cameras. Check for 'zoom creep', where the lens barrel slides under its own weight, which is common in older push-pull designs. SDS inspects the internal glass for haze or fungus, which frequently affects vintage Zuiko optics. We also ensure the aperture blades are free from oil and snap shut quickly, and that the manual focus ring operates smoothly without any gritty sensation.
