The new field depth
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.
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.
