This is a NIKON AF NIKKOR 50mm f/1.8 lens. Although it's an older lens, it's great as a standard lens, offering a light feel and sharp image quality. The bokeh at f/1.8 is softer and nicer than at f/1.4. It's been used very little, so there are almost no scratches or dirt. A protective filter has been attached since I bought it. The lens cap is ZEISS.
