Long portable ENG lens

The KJ22ex7.6B is a telephoto lens covering a generous range of focal lengths while also providing a modest wide-angle of almost 65 degrees in the 16:9 HD image format. This provides a very flexible image framing range, especially for outdoor applications. The KJ22ex7.6B has an excellent balance between size, weight, and HD optical performance intended for HD News and many HD production applications.

The KJ22ex7.6B deploys Large Diameter Aspherical lens elements that contribute to better control of chromatic aberration, geometric distortion, and corner resolution. The curvature of the field and chromatic aberrations have been reduced by the use of special optical materials that include Fluorite and Hi-UD glasses.

Optical Technologies

Newly developed optical glass materials each having unique dispersion characteristics allowed improved control over chromatic aberrations and geometric distortion. Lens element surface accuracy has been improved contributing to improved MTF performance. New Multilayer Optical Coatings combined with new deposition processes produce an improved optical contrast ratio.

Digital Technologies

Enhanced Digital Drive technology provides precision control of the three servo systems for zoom, iris and focuses while also facilitating new developments in lens-camera correction of lateral chromatic aberration. Canon’s patented Micro Roofmirror Array (MRA) technology underlies the unique miniature 16-bit rotary encoders that are used for each of the zoom, iris, and focus position detection (each with a positional accuracy of 0.1 micrometres). Dynamic Zoom Speed Range can be adjusted from 0.5 seconds to 5 minutes (from wide to telephoto extremes)

Optomechanical Technologies

The Digital Drive Unit was totally redesigned ergonomically to facilitate greater comfort and improved actuation of lens controls and provides a wider separation that allows the other hand to more easily adjust the focus control. Special Magnesium alloy body delivers light weight and exceptional durability

Ecological Design

All contemporary Canon lenses avoid the use of materials and substances potentially harmful to the environment. Lead has been removed from all optics and other identified substances from all components comprising the composite lens system.
