The Nikon 35mm f2.8 PC-Nikkor is a manual focus lens with a shift mechanism built in, designed to help avoid perspective problems when photographing architecture: instead of tilting your camera up and creating converging lines, you shift the lens up and keep everything straight. You can also use this as a perfectly fine 35mm f2.8 lens and never shift it, of course. Manual focus, without meter coupling. In excellent condition, with light paint wear, clean glass, smooth focusing.
