This lens is a new milestone in the history of optical design that achieves previously unattainable values in all technical performance characteristics. For instance, there is practically no fall-off at the edges - even at full aperture - in the MTF curves for image sharpness. Even the finest details are rendered with more than 50% contrast - a previously unheard of value that confirms the exceptional properties of this lens.
This enormous contrast enables extremely sharp images with superb corner-to-corner detail rendition in all photographic situations. At the same time, the apochromatic correction of the lens minimises chromatic aberration on sharp edges to ensure natural rendition of every detail. This results in outstanding pictures - even in large-format prints. The Leica APO-Summicron-M 50 mm f/2 ASPH. provides discerning photographers with a new high-performance lens in the portfolio of standard focal lengths.
Peter Karbe, head of Leica optical systems development, and photographer Peter Ferreira have tested the Leica APO-Summicron-M 50 mm f/2 ASPH. for us in advance. Take a look here and compare the personal opinions, formed independently of one another, of a developer and a photographer on the new M-Lens.
