Leica APO-Summicron-M 50mm f/2 ASPH. Lens
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 cushion), 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.
Precision in Perfection
The APO-Summicron-M 50 f/2 ASPH. is considered to be the benchmark in its class. Developed to correct even the slightest color deviations, it achieves image quality that remains unmatched, even on high-resolution sensors. Each subject is rendered with clarity, sharpness and neutral tonality – precisely where expression meets precision.
The Strengths of the 50 mm M-Lens
Thanks to its apochromatic correction, the APO-Summicron-M 50 f/2 ASPH. delivers exceptionally high sharpness while remaining entirely free from colour fringing and aberrations, even with a wide-open aperture. The f/2 lens speed enables separation with soft, unobtrusive bokeh. Its compact dimensions and well-balanced weight make it a reliable tool for portraits, reportage and everyday photography. The neutral colour rendering makes this lens a dependable companion for diverse photographic expression.
Design of the APO-Summicron-M 50 f/2 ASPH.
The optical system comprises eight lenses arranged in five groups, incorporating an aspherical surface and multiple glass elements with anomalous partial dispersion. Precise manual focusing and a close focus distance of 0.7 metres offer meticulous control over light, sharpness and background separation. This carefully crafted masterpiece is handmade in Germany from solid brass and aluminium, built to the most exacting standards with uncompromising passion.
