The Canon KJ10EX4.5B IRSE A 2/3" Portable ENG 10x Zoom Lens is a portable HDTV production lens within the 1/2-inch image format sector of the HDgc family. This particular lens delivers a generous range of focal lengths combined with an exceptional wide field of view in a lightweight mobile package. The KJ10EX4.5B offers focal lengths up to 90mm (with the built-in extender) and a wide-angle of almost 62 degrees horizontal.
The KJ10EX4.5B utilizes new technologies and computer-aided design techniques to produce a very wide-angle HDTV lens. It is a design directly responding to the expressed creative desires of broadcasters and HD producers for more versatility in an HD acquisition system. The KJ10EX4.5B represents a compromise between the demands for mobility in a handheld HDTV camera system and the high imaging performance requirements for HDTV production. The KJ10EX4.5B has a high MTF (Modulation Transfer Function) 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 crisp and clear HD pictures.
