The very high-speed and compact LEICA SUMMILUX-M 24 mm f/1.4 ASPH. M-Mount lens gives photojournalists a new tool for their work. The lens is ideal for available light photography. Like the 21mm f/1.4, it consists of ten lenses in eight groups. Until the advent of state-of-the-art blank-press methods for aspherical lenses, it was not possible to create these new Summilux-M lenses. Hand assembled in Solms Germany, this meticulous craftsmanship also ensures long term reliability even in challenging conditions. The correction of colour imperfections requires a great deal of effort, and to that end this 24mm lens incorporates five separate lenses with anomalous partial dispersion. As a result, vignetting and distortion, the parameters traditionally difficult to control in fast wide-angle lenses, are corrected so well that they are hardly noticeable in practice. Even at an f-stop of 2.8, in effect, only natural vignetting is present. Patented rectangular lens hoods fit Series VII filters.
