The intricate optical design and construction of the lens are responsible for its outstanding sharpness and imaging qualities. The Leica Super-Elmar-M 21 mm f/3.4 ASPH. is constructed with eight lenses in seven groups. At the same time, the use of one lens element with two aspherical surfaces and four lenses with anomalous partial dispersion ensure that aberrations are reduced to an absolute minimum.

As with all Leica lenses, the Super-Elmar-M 21 mm f/3.4 ASPH. was designed and developed by Leica specialists in Solms, Germany, and represents the perfect combination of optical and technical expertise. Particularly reliable and with enduring value, every Leica lens is manufactured from only the highest quality materials and is assembled with meticulous precision, completely by hand. The combination of cutting-edge technologies and extremely thorough manufacturing processes guarantees consistently excellent quality.

The LEICA SUMMILUX-M 21 mm and 24 mm f/1.4 ASPH. are remarkable high-performance lenses. They combine the advantages of ultra-high speed, such as selective focus and excellent available light capability with outstanding imaging and extremely wide angles of view. This extraordinary potential makes the new Summilux?M lenses simply indispensable for the professional M photographer. Their special reliability and value retention is the result of using high-quality materials and intricate assembly by hand at the Solms factory. The combination of state-of-the-art technology with meticulous craftsmanship based on skill and experience guarantees the constant quality of every single Leica lens, once again widening the creative potential of Leica M photography.

The Macro-Elmar-M 90 mm f/4 can be used as a compact 90 mm telephoto lens or, in combination with the Leica Macro-Adapter-M, for macro shots up to a magnification of 1:2. Either way, the lens provides an incredibly high imaging performance.

Without the adapter, the Leica Macro-Elmar-M 90 mm f/4 is an extremely versatile telephoto lens ? for example, for portraits with shallow depth of field and in travel photography for capturing details in landscapes. For reportage photography, the Leica Macro-Elmar-M 90 mm f/4 allows photographers to capture discreet shots at a greater distance from the subjects. The Leica Macro-Elmar-M 90 mm f/4 is a compact and lightweight alternative to existing Leica M-Lenses of this focal length. When not in use, the lens can be collapsed to save valuable space in the camera bag.

Apochromatic colour correction and an aspherical lens surface are combined for the first time in this lens of this type. Of its five individual elements, two are made of high-refraction glass, while two others feature anomalous partial dispersion. Its brilliance and quality of resolution are exemplary even at full aperture. Light falloff is very low. Its fast aperture, for a 90mm lens, lets you shoot at relatively short exposure times even in dim light, helping to minimise the effects of camera shake, for instance when photographing street scenes from a distance.

The new Summilux-M 90 f/1.5 ASPH. enables portraits with a breathtakingly shallow depth of field ?allowing for the subject to be emphasized inperfect focus whilst rendering the background in anappealing blur. The optical design of the Summilux-M 90 f/1.5 ASPH. is at the cutting edge of lens technology, delivering outstanding levels of optical performance even at fully open aperture; in addition, its short telephoto focal length not only facilitates perfect portraits, but also enables Available Light photography, while its minimum focus distance makes it possible to bring out intricate details for unique compositions.
