This is a great S2 rangefinder with the fast Nikkor-S 5cm f1.4 lens. The S2 has several improvements over the S, the big one being a much larger viewfinder. It is a beautifully made classic rangefinder with excellent lenses for a lot less than a Leica. It works very well.
This camera is in unusually good condition. It is not quite mint, but it is not far off. There are just a few light marks on the body and no dents nor big scuffs.The shutter is strong and accurate at all speeds. The lens is clean and scratch free and the aperture is dry and smooth. The rangefinder is bright and accurate.
This is the one you want.
