A World's First
When the minds at Leica set their sights on innovation, they don't just aim to improve: they aim to set new milestones and create masterpieces of photography. That's exactly what they've done with the Leica Super-APO-Summicron-SL 21 f/2 ASPH. — the world's first APO lens with a 21mm focal length.
No Compromises on Performance
This high-performance wide-angle lens captures images and videos with superior optical performance. Its broad viewing angle offers stunning perspectives and intricate detail. True to Leica's APO lens pedigree, it delivers exceptional contrast even when the lighting is less than ideal, opening up creative possibilities through exact control of focus and bokeh. Natural skin tones, smooth gradients, and corner-to-corner sharpness come standard with Leica APO-Lenses. They have everything a demanding photographer needs, whether you're shooting landscapes, interiors, architecture, or engaged in photojournalism and studio work.
Construction in Detail
With 14 carefully engineered lenses — three of them aspherical — arranged in 11 groups, this lens offers peak performance right from the widest aperture settings. What sets it apart is its apochromatic correction, making it the world's first 21mm APO lens designed for full-frame cameras. To eliminate chromatic aberration, most of the lens elements are made of a special custom glass featuring anomalous partial dispersion, made possible by cutting-edge manufacturing techniques and sophisticated workmanship.
