A versatile performer
The outstanding quality, large angles, and compact dimensions of this 21mm Summilux lens makes 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.
The Summilux-M 21mm f/1.4 ASPH. consists of ten lenses in eight groups and incorporates five separate lenses with anomalous partial dispersion. As a result, vignetting and distortion are both excellently corrected. The floating element retains the lenses’ high resolution, even in the close-up range. A patented, rectangular lens hood fits Series VIII filters.
