The Leica Summarit 70 mm 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 eight lens elements of the Leica Summarit-S 70 mm f/2.5 ASPH. CS are arranged in six groups. Two cemented elements made from glasses with high anomalous partial dispersion minimize chromatic aberration, while glasses with extremely high refractive indices and an aspherical element counteract monochromatic aberrations. The built-in front filter is an integral part of the optical design and provides optimum protection against dust and spray. In this design, focusing in combination with a floating element ensures excellent performance in the close focusing range.
