This is a Canon EF mount 24-105mm f/4L IS USM zoom lens with image stabilization. It is a junk item. Neither autofocus (AF) nor manual focus (MF) are working. From a layman's perspective, there are dents and scratches on the exterior, but no mold. There is some dust, but I think it's in a clean condition. Includes the original lens protector, hood, and cloth case. Price is not negotiable.
