This is very similar to the Leica IIIC but adds a unified viewfinder with three levels of magnification. To my mind, that is an improvement over Leica. In terms of quality and finish it is similar. This camera is in beautiful condition and works perfectly. The shutter is accurate at all speeds. The rangefinder is accurate. It is contrasty. It is not the brighest but it is comparable to a Leica. This is a great camera.
