Canon U.S.A., Inc., a leader in digital imaging, has introduced the competitively priced KJ20x8.2B KRSD 20x portable HD zoom lens, which is designed to support the new generation of affordable professional 2/3-inch HD acquisition systems. The KJ20x8.2B KRSD is ideal for wedding videography, corporate and educational production, and broadcast ENG. The newest model in Canon’s cost-effective HDgc Series of portable HD lenses, the KJ20x8.2B KRSD provides sharp, clear optical performance and operator-convenience features designed to rival those of “packaged lens” systems. Impressive features of the Canon KJ20x8.2B KRSD include its 8.2mm wide-angle of view, 20x zoom range, and distortion-free peripheral brightness and peripheral resolution from intermediate zoom to telephoto. Weighing only 2.75 lbs. (1.25 kg), the KJ20x8.2B KRSD also features Canon Advanced Drive Unit technology for fast 1.0 second zooms, quiet operation, and other enhanced shooting capabilities.
“The professional HDTV production market is diverse and increasingly value-minded,” observed Yuichi Ishizuka, executive vice president and general manager of the Imaging Technologies and Communications Group, Canon U.S.A. “The new KJ20x8.2B KRSD portable HD zoom lens marks a price-performance breakthrough for the many production applications seeking excellent picture quality from the new generation of lower-cost third-party HD camcorders. Designed with special advantages for such cameras, the KJ20x8.2B KRSD combines advanced optical technologies, innovative operator-convenience features, and a competitive price that makes it attractive to a wide range of users.”
The exceptional optical performance of Canon’s new KJ20x8.2B KRSD portable HD lens is the result of Canon’s world-leading design tools, including cutting-edge optical-simulation and 3D-design technologies, novel optical glass materials and coatings, and extraordinary dispersion glass (which Canon also uses for its flagship HDxs series lenses). Collectively these technologies and materials have facilitated a high degree of optimization of the cost-performance ratio of the new KJ20x8.2B KRSD. The lens has minimized axial and lateral chromatic aberrations, coma aberrations, and geometric distortion. Chromatic aberration is suppressed across the entire lens surface, enabling sharp images with minimal distortion at any object distance. An optimal balance of resolution and contrast in peripheral areas of the image enables users to achieve crisp, clear pictures. Unique Canon optical materials and multilayer optical coatings used for the KJ20x8.2B KRSD effectively attenuate optical artifacts such as ghosting, flare, and veiling glare that might be stimulated by strong light sources (for example, sun in daytime and car headlights at nighttime). The KJ20x8.2B KRSD exhibits a high MTF (modulation transfer function) at picture center that is also well controlled, out to picture extremities. This high MTF is well sustained even with operational adjustments of focal length and object distance. The KJ20x8.2B KRSD features a focal length of 8.2-164 mm, which is well balanced for both near and distant subjects and provides exceptional rendering of distant subjects at wide angles – frequently required for landscape and cityscape shots.
