The exterior is in good condition. It works properly. I cleaned the lens with a lens cleaner. There is some damage to the coating on the middle element of the lens, but I don't think it will affect taking pictures much. Please refer to the photos. The glass is clear. There are no noticeable scratches on the lens. There is no mold or fogging inside the lens. There is no balsam separation inside the lens. Please refer to the test photos.
