HD Optical Performance with a 100x Zoom Ratio The DIGISUPER 100 xs is a powerful field lens that utilizes Canon’s unique optical design concept, the "Power Optical System" with "x-Element". By adopting this concept and advanced technology, The DIGISUPER 100 xs has improved the range of focal length from 9.3mm-930mm and also has succeeded in compensating the chromatic aberration to a very high accuracy. The superior optical capacity also allows the lens to offer a maximum relative aperture of 1.7 and a minimum object distance of 3.0 meters. Moreover, the DIGISUPER100 xs is almost the same size and weight as the DIGISUPER 86 xs. Canon considers that, no matter how prominent the specifications, if the lens is huge and massive, it is meaningless as a production tool.
