Considered amongst Leica aficionados as one of Leica's most accomplished wide-angle lenses, the Leica 21mm f3.4 Super-Elmar-M Asph Lens offers a wholly professional and premium construction that can produce stunning, crystal clear and colour-rich images that are free of distortion. This lens sees a sophisticated optical design that is encased in a compact, sleek and lightweight frame. In fact, this lens features a double-sided aspherical element that not only reduces the appearance of spherical aberrations, but it contributes to its 5.3 x 4.3cm size. As an M-mount lens, it is compatible with the likes of Leica's M10, of which it seamlessly flows with the look and feel, adding to the premium nature of the Leica brand; a quality that is difficult to recreate.
