Sigma 2x Teleconverter for Nikon F Mount It's as beautiful as the photos show. (Exclusively for Sigma F-mount lenses) There is no mold, scratches, or dust/debris. Since it has been used, there might be some tiny dust particles if examined closely with a loupe, but they haven't affected the photos taken. Includes the teleconverter body, front and rear caps, instruction manual, and box. When not in use, it has been stored in a dry box.
