Olympus 14-45mm F3. 5-5. 6 lens for 4/3 cameras. It will not work on M 4/3 cameras. Cosmetic Condition: Lens has been used. It shows normal wear on the lens barrel from use. Lens front plastic ring is cracked, so lens filter threads are damaged. But lens still accepts filters. I would rate it at 6 (or above average) on a scale from 1 to 10. Front glass has no visible scratches. No fungus or haze. And I don't see any dust particles inside. Lens looks very nice. Lens still makes very nice pictures. The only problem I see, that it's front threads are damaged. It seems that lens has been dropped. If you don't like lens for any reason, you can return it for a full refund. It comes with 90 day money back guaranty. Lens Performance: Aperture blades are snappy, blades are free of oil. Blades open and close properly. Manual focus is smooth, without any play. Everything works good. Lens has been fully tested by our tech guys. I guaranty that it will arrive as described or your money back. All out store items come with 90 day money back guaranty.
