Nikon New Nikkor New Ai converted 28mm f/3.5 wide-angle lens. The exterior has some scratches and marks. Please judge from the photos. All functions are working perfectly. The focusing ring is smooth, The aperture blades are smooth, No oil stains. Optics: No mold, no haze. No balsam separation. There are some scratches on the front element. There is something like a hair on the rear element. Although there are some scratches on the lens, I don't think they will significantly affect the photos. Overall, I think it's equivalent to Excellent 3-5 based on the exterior, functionality, and optics. - Brand: Nikon - Model Name: Nikkor 28mm f/3.5 - Lens Diameter: 28mm - Maximum Aperture: f/3.5 - Lens Cap: Included - Lens Type: Wide-angle lens Thank you for viewing.
