Leica Summarit-S 70Mm F/2.5 Asph Cs Lens

Standards redefined The Summarit 70 f/2.5 ASPH. (CS) (56 mm in 35 mm format) is suitable as a standard focal length for an enormous range of photographic situations and, thanks to its speed and superior imaging quality, masters them at all apertures and focusing distances. The use of aspherical surfaces to almost completely eliminate monochromatic aberration is unusual for this focal length and underlines the exceptional character of this lens. The highlights Ideal standard for all photographic needs High-performance standard lens with an angle of view equivalent to that of a 56 mm lens in 35 mm format Innovative central shutter for maximum design freedom when using additional light Excellent imaging performance over the entire range and at all aperture settings Extremely fast Creative use of sharpness and blurring for the plastic extraction of motif details Best image quality up to the edges due to aspherical optics Weather- and dust-sealed lens Anything but standard The Leica Summarit-S 70mm f/2.5 ASPH. is the ideal standard focal length for all photographic needs. Its extreme speed and excellent imaging performance guarantee outstanding results at all apertures and distances. The incorporated aspherical element almost completely eliminates monochromatic aberration and emphasises the exceptional character of the lens. Technical details The eight elements of its optical system are arranged in six groups. Two elements are made from glasses with high anomalous partial dispersion minimise chromatic aberrations. Glasses with high refractive indices and one aspherical element prevent monochromatic aberrations. Excellent close-range performance is guaranteed by the combination of a floating element with full-system focusing.
