The exterior is in good condition. It works properly. The lens was cleaned with a lens cleaner. There is a slight trace of mold on the front of the lens, but I don't think it will affect photography 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.
