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 work perfectly. Focusing is smooth, Aperture blades are smooth, No oil stains. Optics: No mold or fogging. No balsam separation. 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, operation, 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.
