The Olympus Zuiko Auto-S 50mm f/1.4 lens offers high-quality imaging with a bright maximum aperture. *Price negotiations are not accepted for immediate purchase.* **This is an OM mount lens for the OM-1, not a Micro Four Thirds lens.** Appearance: It's clean. There appear to be no noticeable scratches or marks. Lens (Please forgive my amateur inspection): There is some minor dust accumulation due to aging, but there appears to be no mold or haze. Operation: The focus ring and aperture ring operate smoothly with appropriate torque.
