Nikon 50mm 1.4 AI Nikkor format_Digital Medium Format This is a modern 40mmThis Nikon 50mm f. 14 AI Nikkor is in decent condition, with some paint wear, a few small barrel scuffs, and very slightly uneven focus feel. Front element has a few small coating marks which will not affect imaging. No haze, no fungus, clean diaphragm. It's not perfect, but it's shootable, and image quality is nice.
