I purchased this lens used about 6 years ago. All parts function without any problems. The aperture ring clicks smoothly. There is some dust inside the lens, but I don't see any visible mold. There is some slight haze, which will result in a softer image. Please understand this as a characteristic of this lens. Focus at infinity at the widest aperture does not work. This was the case since I bought it. I don't know if it's a defect or a specification. A Marumi protective filter, an aftermarket lens hood, and a slip-on lens cap that matches the aftermarket hood are included. I'm not very knowledgeable, but please ask if you have any questions. I was using it with a Sony E-mount using a lens adapter. The adapter is not included.
