Nikon 58mm f1.2 Noct-NikkorNikon 58mm f1. 2 Noct Nikkor lens in excellent condition, with very minor barrel paint wear, clean glass with minor dust, good diaphragm. The Noct Nikkor is a classic aspherical lens designed to minimize spherical aberration and sagittal coma wide open, ideal for night photography and other demanding low light applications. Nikon has a nice writeup on their historical site. A rare lens in pretty solid shape.
