Thank you for viewing. OLYMPUS M-SYSTEM E.ZUIKO AUTO-T Mount: OM Mount Focal Length: 135mm (Single Focus) f-value: F3.5-22 Focus: Manual Focus Included Accessories: ・Original dedicated case (with some damage to the lid) ・Lens cap (Canon) ・Mount cover (OLYMPUS) ・Lens protector (NIKO LMC-1 49mm) I received this as a gift, so I don't know the actual usage, but the exterior shows little signs of use and is in excellent condition. The focus ring moves smoothly throughout the entire range. There is no oil on the aperture blades. A lens hood is built-in, and the lens hood extends when you pull out the ring on the front element side. A Canon lens cap is included. There is some small dust when viewed in strong light, but it does not affect shooting, and the optics are generally in a clean condition.
