This Nikon 55mm f/1.2 was Nikon’s first ultra-speed f/1.2 lens. Nikon has never made a faster SLR lens, it’s merely made them in slightly different focal lengths of 50mm and 58mm. Nikon replaced this lens with today’s slightly smaller 50mm f/1.2 AI-s in the spring of 1978. It performs about the same.
