Main Features -The new YJ20x8.5B is a long zoom portable 2/3-inch lens offered by Canon to support a broad diversity of professional, business and industrial production applications. It is the latest member of a family of portable Pro-Video lenses that collectively offer an affordable broad range of creative options. -The new YJ20x8.5B utilized advanced optical technologies and powerful computer-aided design techniques to produce a high-performing lens in an impressive 2.58 lb package, a full 11% lighter than its predecessor, the YJ19x9B KRS. It uses the Canon-renowned 3-group Internal Focus system. It is a design directly responding to the expressed creative desires of a broad cross-section of producers for a versatile acquisition system. ABOUT THIS LENS -The new YJ20x8.5B represents an excellent compromise between the demands for high sensitivity (maximum relative aperture of f 1.8) and mobility in a lightweight handheld camera system that can address a wide diversity of corporate, business & industrial, and some broadcast applications -The new YJ20x8.5B KRS offers the widest focal length (8.5mm), highest zoom ratio (20x) of any lens in its class as well as the fastest servo zoom speed (1.2 seconds, end to end). In addition, the lens offers a generous horizontal field of view of 54.7 degrees. The optical optimization strategies achieved an excellent MTF profile over the entire image plane, minimization of chromatic aberrations, and maximization of image contrast. Contrast was extended by superb control of black reproduction – with optical and mechanical design innovations that substantially reduced flare, veiling glare, and any internal reflections. -The new YJ20x8.5B KRS also features a new and exclusive ergonomically designed drive unit. The drive unit will not only fit into the palm of your hand more comfortably, since it is smaller, it improves the feeling of unity between the drive unit and the lens. The drive unit, featuring a grip support and ribbed surface, is tilted at an ideal angle in order to achieve a better balance and to provide more comfort to the operator. |
