This is a Leica M-mount lens. Since I don't have an M-mount body, I'm listing it in this category. This is a rare, early model, one of only 222 produced in 1958. Stored in a dehumidified cabinet. The Super Angulon is cool. Exquisite construction, click sound, torque, infinity lock, and materials. Everything is perfect. I had it in my collection, but I'm selling it to fund the purchase of another lens. This is a rare find in this condition. ▫️Appearance▫️ There are minor scratches commensurate with age, but no major damage, giving the impression that it's clean for its age. If I had to point out something, there's a slight scratch on the 0.4m indicator, but it's barely noticeable unless you look closely in the light. I cleaned each of the knurled parts, so it's cleaner than when I bought it. 1. Aperture operation and click sound: No problems. 2. Body play: None. 3. Helicoid: Easy to operate with a moderate torque feel. 4. Stopper: Locks properly. 5. Aperture blades: No scratches or abrasions. 6. Paint loss: Present, as shown in the photos. It might have a slight effect in backlight, but I couldn't compare, so I didn't notice it. ▫️Optics▫️ Angulon lenses often have haze, but this one is clear and sharp. Even with an LED light, it seems clear. However, there is one scratch in the middle of the inner lens. I didn't notice it in my photos, but please check the sample photos and purchase with your understanding. ▫️Accessories▫️ 1. Genuine lens hood 2. Genuine rear cap ▫️Notes▫️ I am not a professional, so the condition is based on my subjective assessment. Also, this item has been handled by someone else, so please check the photos carefully and purchase with your understanding. The color may appear different depending on your monitor and the light source used for the photos. I will post plenty of photos so you can see the colors as accurately as possible, so please understand before purchasing.
