Leica 35mm f1.4 ASPH (E46) Lens Overview

The ultimate in lens design
This lens is among the very best in terms of sheer quality of design. Its exceptional picture performance in such a compact package is an outstanding achievement of Leica's aspherical technology. The hallmarks of this remarkable lens include high contrast, superb detail rendition across the image field, excellent flatness of field, and very low coma - all at virtually the same quality even at distances down to 0.7 meters (28 in). The 35 mm focal length is already the standard for many Leica photographers. Ultra-high speed paired with outstanding optical characteristics and compact dimensions make this Summilux a universal wide-angle lens. Its uses range from medium-distance portrait photography to landscape shots. We can recommend it without reservation as a top lens, best suited for available light photography.
