The LEICA APO-Summicron-M 50mm/f2 ASPH will offer photographers the following advantages:
• High speed standard lens delivering outstanding imaging performance
• Supremely soft rendering of blurred image areas (Bokeh)
• Integrated lens hood, extendable by rotating
• Product package includes milled brass lens front cap
• Exclusive presentation packaging box
The LEICA APO-Summicron-M 50 mm/f2 ASPH was designed like all Leica lenses with the aim
of maximizing both contrast and detail even at full aperture. That aim is met in an incomparable
manner. The latest milestone in the history of the M-system delivers previously unattained
performance levels in terms of all technical parameters. The MTF curves, which describe the
sharpness of the image, remain all the way to the edges, even with the aperture open, over
50% contrast. This level of performance has never been achieved previously and
demonstrates the exceptional quality of the lens. This allows extremely sharp imaging in all
scenarios, with optimal definition right into the corners, even for close-ups.
This lens has an apochromatic correction feature which is a highly complex and sophisticated
method of color error correction. It minimizes color fringing at sharp edges, so ensuring that all
details are naturally depicted. This is achieved, among other means, by skilfully integrating
glasses with anomalous partial dispersion into the lens design. All these qualities allow
photographers to get the best possible image quality, especially for large prints.
The Leica APO-Summicron-M 50 mm/f2 ASPH particularly in combination with high-resolution
cameras such as the new Leica M Monochrom will offer photographers the opportunity to
produce fine-art photography of a quality never before attained.
