Powerful ENG Lens for Affordable Budget HD Productions

The KJ17ex7.7B is specifically designed for users whose foremost priority is a lens that delivers a generous range of focal lengths combined with a wide field of view in a lightweight mobile package. The lens design is a fine compromise between the demands for ruggedness and mobility in a handheld camera system and the high imaging performance requirements for HD News and affordable budget HD productions. An important aspect of this lens is the cost optimized design concept. Customer recommendations combined with evolving optical design strategies and materials produced a new definition in price performance ratio for HD ENG acquisition systems that guided the design of the new KJ17ex7.7B.

Improved Optical Performance

Compared to its predecessor KJ16ex7.7B lens, the optical performance of the KJ17ex7.7B has been improved on a number of fronts. Utilizing special optical materials such as "Fluorite" and "Hi-UD" (high index ultra low dispersion) glasses, most of the lens elements and optical layout were redesigned using Canon's advanced computer-aided techniques to achieve a new level of optimization. Of particular significance are improvements in monochromatic and chromatic aberrations, producing enhanced image sharpness at picture center and picture extremities. New aspheric lens element designs have helped to further diminish geometric distortion and flare.

Digital Technologies

New third-generation enhanced digital servo systems using Canon-developed 16-bit optical rotary encoder devices introduce new creativity to handheld acquisition systems. Enhanced Digital Drive technology - encompasses a microcomputer driven servo control that embodies position memory and user-defined digital functionality to significantly empower the camera operator. A 16-bit rotary encoder for aperture control reports to the associated camera Iris control system (10-bit compatibility). Maximum Zoom speed is 0.5 seconds.
