This is a Cosina Voigtlander manual focus single-focal-length lens for Leica M mount (VM mount). The rear cap is missing. Please prepare one in advance (filter diameter 46mm, and a front cap if you don't use a hood). The front cap, focusing ring, and dust aside, it's in good condition overall. Stored in a photocatalytic dehumidifying cabinet, no smoking or pets. Unlike the Nokton, it's sharp and high-contrast from the widest aperture. And the design is cool. It's a rare lens with a small number of units, and I don't know the market price, but I will block anyone who tries to haggle too much.
