JUPITER-3 f1.5/50mm Leica L39 mount. No mold, scratches, or haze. There are a few specks of dust, but they do not affect the photos. Sample photos were taken with a Sony αNEX-6, which is APS-C size. Image 10 is f8 at infinity, and image 11 is wide open (f1.5) at the closest distance of 1m. Helicoid is in good condition. Aperture blades have no oil stains. However, there are the following issues: The aperture ring is generally recessed (towards the camera) and has some play. (Images 7, 8) The aperture ring is not smooth. Of course, aperture settings can be made. Please understand the above before purchasing. It comes with front and rear caps, but the rear cap is not an L39 cap, but a lens protection cap.
