This standard lens, available with or without a central shutter, gives priority to top imaging performance for all applications. In addition to an aspherical surface, special glass with anomalous partial dispersion or high refractive power is used. Focusing combined with a floating element provides consistent high contrast performance through the entire working range, from close-up to infinity.


The Leica Summarit-S 70 mm 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. Unusual for this focal length is the integration of an aspherical element. This almost completely eliminates monochromatic aberration and emphasises the exceptional character of the lens.


The eight elements of its optical system are arranged in six groups. Two cemented elements 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.
