The Summilux-M 21mm f/1.4 ASPH is the first and only lens with this size and lens speed. The outstanding quality, large angles, and compact dimensions make it a versatile performer. It works from full aperture - with an extremely shallow depth of field and a subject separated from the background - to a medium stop which can sharply and effectively reproduce entire scenes.
