Rare and unusual Zeiss Sonnar 5.8cm f/1.5 uncoated lens, presumably made during WW2, although there is some debate about the origins of this unusual model. The image quality is great and has signature Sonnar character, with silky smooth bokeh and sharpness matching if not exceeding more common 50mm f/1.5 model. This lens has a L39 Leica rangefinder-coupled 39mm thread mount.
Glass is in excellent shape for its age, clean and clear with no scratches, almost no cleaning marks, no haze, no fungus, minimal dust. Aperture and focusing rings work well and rotate smoothly. Cosmetically it shows some normal signs of age use such as small scuffs and oxidation spots, but overall looks excellent with no serious scratches and no dents.
