Auto Yashinon-DX 50mm f/1.4 | Good Condition | The Japanese Summilux

The Auto Yashinon-DX 50mm f/1.4 is a premium, high-speed prime lens from the golden era of Japanese optics. Often referred to as a "Japanese Summilux" due to its exceptional build and rendering, this lens was manufactured by Tomioka Optical, a legendary factory known for producing glass for Yashica and Carl Zeiss. Featuring an ultra-fast f/1.4 aperture, it is an elite performer in low-light environments and produces a stunning, shallow depth of field. This lens is highly prized by both film purists and digital adapters for its signature "creamy" bokeh and the vibrant, high-contrast colors it delivers.

Specialist Note "The Yashinon-DX 50mm f/1.4 is a true heavyweight in the vintage lens world. It was produced by Tomioka at a time when they were arguably making the best glass in Japan. Unlike many fast fifties that are soft wide open, the Yashinon-DX maintains impressive central sharpness at f/1.4. It has a heavy, luxurious feel that modern plastic lenses simply can't match. When adapted to digital, it produces a lovely 'glow' in the highlights that gives portraits a dreamlike, high-end cinematic quality."

Condition Report Good condition. The all-metal lens barrel shows normal signs of light use and minor surface wear consistent with its age. The optics are clear, with no signs of fungus, haze, or significant scratches. The aperture blades are clean and move snappily, and the manual focus ring operates with a smooth, dampened precision.
