Manufacturer description
The 20mm and 21mm are all-round ultra-wide-angle lenses for best effects at all lens openings. They produce in-depth sharpness of the image throughout the picture area, bringing out a perfect harmony of the main subject with the accentuated remoteness of the objects in the background. Excellent aberration correction and unequalled color reproduction. Particularly recommended for specialized photographic work.
