The Nikon 28mm f3.5 PC-Nikkor is a manual focus wide angle lens with a useful shift ability: when photographing buildings or other tall objects, this allows you to slide the lens up or down instead of tilting your camera, avoiding perspective distortion. You can also use it to create stitchable panoramic images, or just shoot it straight and never mind all that nonsense, because it's still a perfectly fine 28mm lens. In excellent condition, with very minor finish wear, clean glass.
