Thank you for viewing. This is a used item purchased on Mercari. I am selling it because I purchased another zoom lens. *Please note that this zoom lens is a Four Thirds mount, not a Micro Four Thirds mount. It has a used feel appropriate for an old lens. There are scratches. There is dust and debris inside the lens. I don't think there is any mold, at least to the naked eye. It worked with a VILTROX mount adapter on a LUMIX G100.
