Canon Introduces New Zoom Lens

Canon has introduced the KJ22ex7.6B, its newest portable HD lens in the HDgc family.

The KJ22ex7.6B is a multipurpose telephoto lens. The lens encompasses a range of focal lengths while also providing a wide-angle of almost 65 degrees in the 16.9 HD image format. Features include Large Diameter Aspherical lens elements that contribute to a better control of chromatic aberration, geometric distortion and corner resolution. Curvature of field and chromatic aberrations have also been reduced by use of special optical materials that include Fluorite and Hi-UD glasses.

“These lenses retain the robust magnesium optomechanical design of our higher-end lenses, as these cannot be compromised in ENG” said Larry Thorpe, national marketing executive, Broadcast and Communications division. “Canon’s mobilization of contemporary design tools and optical materials have facilitated a significant cost reduction, while still maintaining an impressive overall HD imaging performance.”

The Digital Drive unit enables users to program precise and repeatable settings into the KJ22ex7.6B lens for zoom position, speed, focus, and iris. Improvements include widening the spacing between the focus ring and the Digital Drive unit so operators are less likely to accidentally change settings while manipulating the focus control. Canon’s new software allows the Digital Drive unit within the KJ22ex7.6B to work with chromatic aberration correction systems developed by different manufacturers.
