Leica APO-Summicron-M 50mm f/2 ASPH, black chrome finish #11811

Reminiscent of the vintage Summicron 50mm f/2 (II) from 1956, the APO-Summicron-M 50mm f/2 ASPH, black chrome features the characteristically scalloped focusing ring, with barrel components machined from brass. This special lens has engravings for the focal length and distances measured in feet highlighted with red enamel paint, meticulously applied by hand. The classic package is completed with a vintage-style, round brass lens hood engraved with ‘Made in Germany’ and a lens cap carved from solid brass. The retro-style black chrome version of this lens matches the incredible capabilities and image rendering of the standard Leica APO-Summicron-M 50mm f/2 ASPH, and will be limited to just 700 lenses worldwide.


With the new APO-Summicron-M 50mm f/2 ASPH. our engineers have set new standards in imaging performance. This is the first lens ever to fully exploit the capabilities of modern high-resolution camera systems, making no compromises in image sharpness and achieving previously unattainable values in all technical performance characteristics.

Even at full aperture, there is no fall-off at the edges in the MTF curves. Furthermore, the finest details are rendered with more than 50% contrast, enabling sharp images with superb corner-to-corner detail rendition in all photographic situations. The apochromatic correction of the lens minimizes chromatic aberration to ensure natural rendition of every detail.

More than 30 years after the launch of Summicron-M 1:2/50 mm, which is still available, the Leica APO Summicron-M 1:2/50 mm ASPH. represents a totally new development. With its compact body – only marginally longer and slightly heavier than the Summicron-M 1:2/50 mm, and with an almost identical diameter, it provides visibly higher image quality. On the Leica APO Summicron-M 1:2/50 mm ASPH. the exceptional correction enables all aberrations to be reduced to a minimum level that is negligible in digital photography. Its key features include excellent contrast rendition, all the way to the corners of the image, even with a fully open aperture. The use of a „floating element“ ensures that this is retained, even for close-up shots. Vignetting is limited to a maximum – i.e. in the corners of the image – of just 2 stops at full aperture in 35 mm format, or around 1 on the Leica M8 models. Stopping down to 2.8 visibly reduces this light deterioration towards the edge of the image, with practically only the natural vignetting remaining. Distortion is very low at a maximum of just 0.4 % (pin cushoin), which is practically imperceptible. A total of eight lens elements are used to achieve this exceptional performance. To realize the apochromatic correction (resulting in a common focusing plane for three light wavelengths), three are made of glass types with high anomalous partial color dispersion, while two of the others have a high refractive index. The aspherical surface of the first lens in the rear group helps to reduce spherical aberration and flatten the image field. While the optical construction in front of the aperture is a Gaussian type, the arrangement of the lens elements behind it is similar to that in the Summilux-M 1:1.4/35 mm ASPH. This group comprises a „floating element“, which is moved independently of the rest of the construction during focusing. Summary: The Leica APO Summicron-M 1:2/50 mm ASPH. delivers exceptional picture quality and sets new standards in 35 mm digital photography.
