This is an adapter for attaching Minolta SR mount (manual lenses such as MC and MD) lenses to Leica M mount cameras. I purchased it new on Amazon for about 4,500 yen. It's a beautiful item, used only a few times. Minolta lenses are sold cheaply as junk, so they are suitable for playing with old lenses.
