The highly light sensitive yet compact Summilux M 24 mm f/1.4 Asph is the fastest 24 mm lens ever produced for a rangefinder camera. Launched in 2008, it was particularly aimed at reportage photographers who required a wider angle of view than that offered by a 35 mm lens. In addition, its maximum aperture of f/1.4 makes it the perfect tool for Available Light photography.
With a diagonal angle of view of 84 degrees combined with a minuscule depth of field, the lens offers striking visual results – allowing for a distinctive isolation of the subject while still fully capturing its surroundings.
In order to construct the Summilux M 24 mm f/1.4 Asph, Leica made considerable investments in new tools and production techniques: when creating a lens with such extreme attributes, lens centration and balancing of all elements must be executed with an even tighter tolerance margin than is already customary for all Leica lenses.
Along with the Summilux M 24 mm f/1.4 Asph, Leica also released a series of new mirror viewfinders which use a concave mirror to create illuminated framelines.
