This is the third generation of the Leica Summicron 50mm, a classic Leica lens. It's an M-mount lens, but since I couldn't select that, I've chosen the E-mount. This is a popular German-made lens. I purchased this from Kitamura about two years ago as an AB (Good Condition) serviced item, but I rarely took it out of the dry cabinet. To the untrained eye, there are no noticeable scratches, and I think it's quite clean. I don't think there's any mold, either, but I'm not a specialist, so I'm not very knowledgeable. Please judge from the images. This time, I'm including the Leica dedicated hood 12538 and the Leica lens filter E39 iva 13131. Focal Length: 19-70mm Maximum Aperture: 1.5-2
