Leica Summilux-M 21mm f/1.4 Summilux-M Aspherical 21mm
The lens combines an f/1.4 maximum aperture with a 21mm focal length and a 10-element, 8-group aspherical design, delivering extreme low-light capability and corner-to-corner sharpness rare for such a wide-angle. Its robust all-metal barrel and floating element system keep distortion and vignetting minimal, while the 11-blade diaphragm produces smooth, rounded out-of-focus highlights. This lens is best for environmental portrait shooters who need dramatic subject-background separation with a uniquely immersive perspective.
