Description Technical Specs Product Includes
 
The Canon KJ20x8.5B KRS is a portable HDTV production lens within the 2/3-inch image format sector of the HDgc family. This particular lens is intended for all who have as their foremost priority the use of a very cost-effective and lightweight (2.8lbs for this lens) HD acquisition system for shooting over long distances combined with reasonably wide angle capture. It was specifically designed for the new cost-effective 2/3-inch acquisition systems. It is an important member of the emerging HDgc family in terms of facilitating HD imaging with equivalent operational capabilities as the established 2/3-inch SDTV systems.
Features
The KJ20x8.5B KRS represents a fine compromise between the demands for mobility in a handheld HDTV camera system and the high imaging performance requirements for HDTV production. 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. Relative light distribution was optimized for the more open aperture settings and this uniformity of brightness across the image plane combines with the high contrast and excellent picture sharpness to produce vividly clear HD pictures. Contrast was extended by careful control of black reproduction – with optical and mechanical design innovations that substantially reduced flare, veiling glare, and any internal reflections. Tight control of the geometric distortion at wide-angle settings constituted another central design imperative. The lens spectral transmittance characteristic was closely coordinated with that of all of the major portable cameras to ensure adherence to the HDTV colorimetric standards and to additionally support flexible creative control of color reproduction.
