This is a lens purchased as a lens kit, unused, from this site. Nikon 28mm f/2.8 Special Edition Includes f-foto lens hood and a Nikon genuine lens filter. These two items were purchased new from Amazon. I am selling this because I haven't had much opportunity to use it. There are almost no scratches or stains, and I think it's close to being in beautiful condition. Optically, I don't see any dust or debris from a layman's perspective. There is no mold. Please refrain from purchasing if you are looking for something in new condition. Thank you. Since there is no option for Z mount, I have selected F mount, but it is a Z mount lens. Focal Length: 19-70mm Maximum Aperture: f/2.1-2.8 Other Features: Lens hood included, front lens cap included, rear lens cap included
