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.
