The KJ10ex4.5B and the HDgc line of lens have been specifically designed for low cost tapeless HD camcorders and this lens is particularly well suited to HD Reality TV, newsgathering and other low budget HD productions.
The KJ10ex4.5B very short 4.5 mm focal length translates to a 93.7 degree horizontal angle of view for the 16:9 HD image format. Combined with a focal range cover from 4.5mm to 45mm (and 90mm with extender) this lens offers unsurpassed operational capabilities in a compact package weighing less than 1.84kg.
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.
Enhanced Digital Drive technology provides precision control of the three servo systems for zoom, iris and focus 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 micrometer). Dynamic Zoom Speed Range can be adjusted from 0.5 seconds to 5 minutes (from wide to telephoto extremes)
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
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.
