condition: excellent make / manufacturer: Nikon model name / number: AF Nikkor 20mm f2.8 D Up for sale is this wide angle lens ideal for landscape and group photography. This is a full frame auto focus lens that can also be used on DX format (crop sensor) cameras. The lens has an AF-D mount which allows for either full aperture control with the command dial of the camera, or manual aperture control (ideal for video) or old film camera use, by turning the ring itself. Please note that auto focus is not supported on entry level DSLRs like the D3000 and D5000 series. All mid grade DSLRs and the pro series are fully compatible with this full frame lens. As you can tell from the photos, this lens is in excellent condition with no scratches or fungus on or inside the glass. Light scuffs on barrel. As grading is subjective, I photographed all sides for you to make your own cosmetic assessment. Operationally, the focus is sharp. Since this a mechanical auto focus, it's a touch noisier compared to autofocus lenses with built in motors. Aperture is snappy This sale includes: 1 - Nikkor 20mm F2.8D AF lens serial #318332 1 - Front Lens Cap 1 - Rear Lens Cap Price is firm - serious inquiries only
