Design Details

Fourteen carefully engineered lens, three of which have aspherical surfaces, arranged in eleven groups, provide the highest degree of image quality, even at the widest aperture setting. Its apochromatic correction is unique among super wide-angle lenses, making it the world’s first 21 mm APO lens for full-frame cameras. For perfect correction of chromatic aberration, most of the incorporated lens elements feature anomalous partial dispersion and are made of specialised glass elements, crafted with cutting-edge manufacturing techniques and sophisticated workmanship. The close focus distance is only 21 cm, enabling striking composition of foreground elements. The quiet, accurate autofocus allows the focus to be set precisely for architectural and landscape shots. The aluminium housing is made for demanding outdoor use as it is sealed against dust and splash water.
