Sharpness from Corner to Corner

The new field depth

With the new APO-Summicron-M 50mm f/2 ASPH. Leica 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.

Technical details

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.


Innovation born of tradition

Uniting decades of rangefinder technology experience with innovative digital technologies, the new Leica M features a freshly developed high-resolution full-format CMOS which delivers impeccable imaging results. Now featuring Live View, video and new focusing methods, the M merges craftsmanship and innovation.
