When the APO-Summicron-M 50 mm f/2 Asph was introduced in 2012 alongside the M Monochrom and the M (Typ 240), it offered the most exceptional imaging results of any M lens to date.
The MTF graphs, which illustrate the contrast rendition of fine details (and thereby the sharpness of the image), confirm the lens' outstanding performance: even the finest details are recorded with contrast levels of more than 50% across the entire image plane. In addition, the apochromatic correction of the lens minimises colour fringing along sharp edges, ensuring a natural rendition of every detail.
The new lens design of the APO-Summicron-M 50 mm f/2 Asph was based on the optical calculations of its predecessor, which had been on the market since 1979 – and whose classic specifications of a 50 mm focal length and maximum aperture of f/2 represented the ideal starting point for further development.
The lens construction was based on both the Summilux-M 50 mm f/1.4 Asph and the Summilux-M 35 mm f/1.4 Asph – for example, the new APO-Summicron also featured a floating element.
