‘NEW’CANON'S SECOND GENERATION HDgc SERIES KJ17ex7.7B

NEW GENERATION CANON LENSES FOR BUDGET HD

KJ17ex7.7B  - first ofCanon’s second generation HDgc series

Recognising the constant introduction of new and improved 2/3-inch HD acquisition systems, supported by global experience, Canon is introducing a second generation HDgc series with further design improvements.  The first of these new lenses is the KJ17ex7.7B IRSE / IASE.  

Powerful ENG lens for lower budget HD productions

The KJ17ex7.7B is specifically designed for users who need 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 need 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 feature of this lens is the cost-optimized design concept.  Customer recommendations, combined with evolving optical design strategies and materials, have produced a new definition in price-performance ratio for HD ENG acquisition systems  -and it is embodied in the design of the new KJ17ex7.7B. 

Improved optical performance

Compared to its predecessor, the KJ16ex7.7B lens, the optical performance of the KJ17ex7.7B has been improved on a number of fronts.  Making use of special optical materials such as “Fluorite” and “Hi-UD” (high index ultra low dispersion) glasses, most of the lens elements and optical layout have been redesigned with 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 both at picture centre and picture extremities. New aspheric lens element designs have helped to further diminish geometric distortion and flare.  

Improved operability, reduced operator fatigue

Coupled with these innovations in optical performance is a totally new design of the digital drive unit.  Refined by long-term market research and worldwide experience, Canon have used the latest techniques in 3D CAD-CAM design significantly to improve the human tactile interface with the controls of zoom, iris, and focus.  This has produced the following significant physical benefits: 

        ＊Reduced physical stress

        ＊Superior ergonomic design

        ＊Improved ease of operation
