Leica Blue Coated Summar 5cm f2 Leica L39 screw mount. Can be easily converted to a mount for mirrorless cameras, so please feel free to consult. Released in 1932. It's the predecessor to the famous Summicron, and is known as a quirky and "lost" lens, famous for its strong flares and blurry images that always seem to have a mist. In good condition, it produces circular ghosts when backlit. This is a lens that those who love old lenses should definitely try. This lens has a history of having its front element polished and coated by Yamazaki Optical Laboratory. After many years since receiving polishing and coating from Yamazaki Optical, it has been reconditioned. I have prepared sample photos taken with this lens. I took it to a rose garden in its prime. I tried several Summar lenses on this day, but the Yamazaki Summar's colors are different. In the first half, I experimented with various shooting methods using light. It's not good to keep direct sunlight on the sensor with a mirrorless camera, but... it's fun, so it can't be helped. In the second half, I took close-up shots and shots in direct sunlight. The bokeh is also interesting, and it might be good for the upcoming illumination season. While trick shots are good, I think the Yamazaki Summar, which has undergone coating deposition, is characterized by its ability to capture and reproduce colors well. The front element continues to maintain its beautiful condition, and it's clear that it has been handled with care. There is no noticeable mold or clouding, and it has been finished. If you look closely, there is a slight unevenness in the coating on the rear element surface. I also removed as much dirt as possible. The exterior has scratches on the collapsible barrel, but the operation is smooth. I think you can use it for many years to come. Condition: Yamazaki polished!
