Super-APO-Summicron-SL 21 f/2 ASPH.
With the Super-APO-Summicron-SL 21 f/2 ASPH., Leica Camera AG simultaneously introduces the world’s first APO lens with a focal length of 21 mm. Hence, the high-performance wide-angle lens meets even the highest professional requirements and provides consistent sharpness right into the outer corners of the picture. This way, it becomes the latest family member of the APO-Summicron-SL lenses which stand for top performances in the optical field and impress with their fast, reliable Dual Synchro DriveTM autofocus. Just like the already available lenses with a focal length of 28, 35, 50, 75 or 90 mm, the Super-APO-Summicron-SL 21 f/2 ASPH. has the same compact dimensions with the same E67 filter diameter – despite the extreme viewing angle. This viewing angle of the Super-APO-Summicron-SL 21 f/2 ASPH. is predestined for the challenging use in landscape photography, indoors, during reportages, in the studio and in architectural photography. A closest focusing distance of only 21 cm also ensures effective detail shots while the big maximum aperture allows for additional creative possibilities due to the selective usage of sharpness and blur.
The 14 high-precision made lenses – three of them with an aspheric surface – are divided in 11 groups and contribute to the highest possible degree of image quality even with the aperture fully open. The apochromatic correction of the lens is unique to its focal length and once again proves the highest standards of the Leica engineers. Most of the used lens elements are therefore made of high-quality special glasses whose demanding processing needs the most innovative methods of manufacturing.
Both new lenses enhance not only the SL-System but also the ever-expanding portfolio of the L-Mount alliance with two outstanding ultra wide-angle lenses in order to capture pictures and videos in unique Leica quality.
