This is the beautiful first generation SA with the blade aperture. Note that it goes well into the camera body and vignettes badly on digital. On film, it is great. It gives a sharp and undistorted image and the lens is TINY. This is just the lens, no finder or rear cap. It comes with an original Leica front cap. The lens is in great condition. There is very light body wear. The glass is clean and scratch-free with no haze or fungus.
