| Main Features |
· Powerful ENG Lens for Lower 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 lower 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.
·
Improved Operabilty and Reduced Operator Fatigue
Besides the exceptional optical performance, another remarkable character of this new lens is it’s newly designed drive unit.
With the goal of pursuing ease of operation, Canon has reached a new design based on human ergonomics, refined by a long term research and testing.
