LEICA SUMMILUX-M 21mm/f1.4 and 24mm/f1.4 ASPH - superfast wide-angle lenses:
Their exceptional speed and outstanding imaging performance combined with extremely large angles of view and compact dimensions make these lenses unique. The 21 mm lens is even a world first: it is the first 21 mm lens in 35 mm photography with an initial aperture of f/1.4.

The new Leica Summilux-M lenses have wide application potential, thanks to the
combination of wide-angle characteristics with ultra-high speed. Extremely shallow field depth at full open aperture. This allows the main subject in close focus shots to be effectively detached from the background. Stopped down to medium values, the field
depth range is so great that entire landscapes will be depicted in sharp focus.

Thanks to “floating elements”, the superb performance is kept even at close focal distances.
Vignetting and distortion are hardly noticeable in practice. Both lenses are equipped with a patented, rectangular metal lens hood that accommodates series
VII (24 mm) or series VIII (21 mm) filter mounts.
Use of regular polarizing filters, size E82 (21mm) & E72 (24mm) is possible with special filter
adapters.
