This is a superb Zeiss 50/1.5 Sonnar for Contax and Kiev rangefinders. Light purple coatings. Perhaps a few micro coating scratches or dust specks if examined under intense backlight, but the glass condition is about as good as it gets for a lens of this vintage. No haze, no fungus, and no oil. A tiny bit of scoring on the tips of the iris blades. Has a small nick on the outside of the filter thread, but filters thread on smoothly. A really nice specimen!
