Leica Summar 5cm f2 Old Lens This is a Leica L39 screw mount. Please consult with me as it can be easily converted to a mount for mirrorless cameras. Released in 1932. It's the predecessor to the famous Summicron, and is a well-known "quirky lens" or "lens of confusion," famous for its intense flare and blurry images that always seem to have a haze. Good condition lenses will produce circular ghosts when backlit. This is a lens that those who love old lenses should definitely try. Various versions exist depending on the manufacturing year, with or without coating, chrome, nickel, etc. This is a non-coated model. The lack of coating results in significant flare, making it popular among those who love quirky lenses. I have prepared some sample images using this lens. This has the typical Summar characteristics. When shooting against the light, multiple rings of light appear like a rainbow. If you capture a sun that isn't too strong, you'll get rainbows, and if you let in strong light like on this day, you'll get white rings. At that time, the contrast of the subject is significantly reduced, creating a beautiful world. While sharp images are possible if you meet the conditions, the contrast tends to be low, and I think the main characteristic is this intense flare and ghosting. It may be more difficult to control than a lens in good condition, but it's easy to produce. Recommended for those who want to master a quirky lens. This appearance looks like nickel, but it's ordinary silver chrome that has worn down. You can't tell from the photos, but there are scratches on the surface of the front element, and while there aren't any deep ones, the center looks slightly cloudy. The light diffusion is due to this. The elements after the middle element are clean. Smooth operation. I feel a high level of addiction to this quirky lens. Please consider it. Condition: Light diffusion! A Summar-like quirky lens. Appearance: Scratches in the center of the focus area, please check the photos. Optics: Slight cloudiness on the front element due to the usual issues, the rest is clean. Operation: Operation confirmed with α7 and Leica Ⅲ. Accessories: Front and rear caps Stored in a dehumidified storage box. 4806 #leica #ライカ (Leica) #summar #オールドレンズ (Old lens) ※ All used lenses on sale have been tested with actual photos! ※ The evaluation is subjective.
