Features and Specifications of Summilux-R f/1.4/50mm

The large-aperture standard focal length lens - f/1.4/50 mm - has always had an important place within the LEICA R system. Its field of vision closely approximates that of the human eye, it opens up interesting additional possibilities, above all in poor lighting conditions, and even so, it is compact and comparatively light-weight. The image quality is virtually always outstanding, whether used in landscape or architectural photography, for snapshots or still life. The previous LEICA SUMMILUX-R f/1.4/50 mm has now been replaced by a completely new design of the same name, which exceeds its predecessor"s optical performance by far. This complete redesign addressed not only the optical system but also the lens mechanism. With its elegant appearance, it matches perfectly with the range of modern LEICA R lenses. Résumé: With its improved performance, the new LEICA SUMMILUX-R f/1.4/50 mm adds new value to the range of standard LEICA R lenses and provides a new incentive to exploit the advantages of the standard lens.
