Leica Nickel Elmar 5cm F3.5 Leica L39 screw mount. This model is a nickel Elmar with a slightly golden hue, not the usual chrome. Furthermore, I believe it's an early model without a serial number. Released in 1930, it's the world's first and oldest 35mm interchangeable lens. If you're in love with old lenses, this is one you should definitely try. While it might be thought to have a very strong character in its images, it's actually a lens that produces very straightforward and high-resolution images. I've prepared some sample images using this lens. The light blooming, typical of old lenses, is a very attractive characteristic. First, in monochrome, as it's a lens from the monochrome era. The light blooming leads to rich tonal expression, even giving a sense of sharpness. In the latter half, in color, the blurred light sources and subdued color rendition give a vintage feel. At the end of the sample images, I've retouched them by changing the color temperature; by utilizing the blooming and emphasizing fluorescent colors, it's possible to create a cyberpunk atmosphere, like a street snap from the world of AKIRA, so please give it a try. There are several types of Nickel Elmar, and some can be difficult to use due to interference with LM conversion rings, but this is a countermeasure model, so there's no worry about using it with a conversion. It's a number 4, so it's not the so-called old Elmar. While infinity focus is achieved, rather than using it to push the limits with a high-pixel camera like the M11, I think it's better to load your favorite ILFORD film and use it for monochrome photography. Optics: Cleaning marks on the front element, slight haze on the edges, which I think is what's producing the blooming. Operation is smooth, but it's a shame that the brass is quite exposed due to wear on the collapsible section; if it weren't for that, it would be 100,000 yen... It's a lens with a lot of potential, so I highly recommend it to those who are looking for character in old lenses. Condition: Recommended for monochrome photography! Rare all-nickel. Appearance: Scratches and wear mainly on the collapsible section. Optics: No mold, haze on the edges, some scratches on the front element. Operation: Tested with Leica Ⅲc and α7, Accessories: Front and rear caps Stored in a dehumidified storage box. *All used lenses on sale have been tested with actual photos. *The evaluation is subjective.
