Nikon 105mm f4 Nikkor-P lens for bellows use. No internal haze, no fungus, good diaphragm, a few internal coating lines visible under very bright light which do not affect image quality. These are likely from original assembly, and while theyre worth noting, they wont wreck your image. Please note that this lens is intended for use on bellows- which are not included- and does not have a focusing mechanism of its own.
