JVC GYDV5100U GY-DV5100U 3CCD Professional DV Camcorder (Lens Not Included) Specs and Details

From the Manufacturer The Canon YH16x7 K12U is an extremely lightweight, portable 1/2-inch lens offered by Canon to support diverse program origination. It is a key member of a family of five portable 1/2-inch lenses that collectively support a broad range of business, industrial, and corporate production applications. This particular lens is intended for producers having as their foremost priority a truly lightweight general-purpose mobile production lens-camera system that offers excellent performance. The YH16x7 K12U utilized advanced technologies and powerful computer-aided design techniques to produce a very wide-angle HDTV lens in an impressively lightweight two-pound package. It is a design directly responding to the expressed creative desires of producers for a versatile acquisition system. The YH16x7 K12U represents an excellent compromise between the demands for high mobility in a handheld camera system and the performance requirements for high-end Pro-Video production. This lens provides a 49.1-degree horizontal field of view and a focal range from 7mm to 112mm. The requisite optimization strategies to achieve this balance sought a high MTF over the entire image plane, minimization of chromatic aberrations, and maximization of image contrast. Preservation of the highest MTF at the wider-angle focal lengths (where scene detail can be particularly high) was a special priority. 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. Three significant technologies converge to produce the YH16x7 KRS portable production lens system: Optical Technologies Newly developed optical materials combined with the very latest lens element design innovations and multilayer coatings that produce a superb imaging system. The IFpro logo identifies the deployment of these technologies in the lens.
