The lens is in perfect condition. The glass is free of all defects including scratches, fungus, haze, coating marks, cleaning marks, and separation. There are no dents or signs of abuse on the lens barrel. The shutter operates as it should. The rear shade / filter ring is removable to fit certain cameras (as seen in photos). Its important that if you do remove it to be extra careful as there would be less protection for the element and you cannot set it down on that side.
