Finding a brand new camera from the mid-60s is pretty wild, but the fact that this is an iconic Leica M3 makes this one really special. The Leica M3 was the very first Leica rangefinder to utilize a bayonet mount for fast lens changing—before that Leicas had screw-mount cameras. It was also the first camera that has a combination of viewfinder and rangefinder into a single viewfinder. The M3 also introduced the rapid film advance lever, an automated film counter, automatic flash sync and a hinged back door plate for film loading. The cameras were produced from 1954-1966 and sold around 220,000 units in that time. Many of them are still in action today.
