Canon reveals the KJ20x8.2B KRSD lens

Canon has launched the new KJ20x8.2B KRSD – a multipurpose 2/3-inch HD zoom lens. The new lens is ideal for camera operators in applications such as wedding and corporate videos, education films and documentaries. Its 20x zoom lens offers a 1.0 second maximum speed over its entire zoom range, alongside a Minimum Object Distance of 0.9M (10mm with Macro). Focal lengths range from an extra-wide angle 8.2mm (60.7 degrees angular field of view horizontal in 16:9 aspect ratio) to 164mm, combining with a f/1.9 maximum reflective aperture. The KJ20x8.2B KRSD weighs 1.25 kg. With tight control of MTF across the entire image plane, a minimisation of chromatic aberrations and the maximisation of image contrast, the lens delivers superb levels of picture sharpness. Contrast is maximised thanks to substantial reduction of flare, veiling glare and internal reflections. The lens offers tight control of the geometric distortion at wide-angle settings, while spectral transmittance characteristic is to HDTV colorimetric standards. With relative light distribution optimised for more open aperture settings, uniform brightness, excellent picture sharpness and high contrast, operators can be sure of producing vividly clear HD pictures. A new optical design includes the precision optical element and multilayer coatings, as well as Canon’s Internal Focus – a floating optical system that improves control of chromatic aberrations. The lens also incorporates Shuttle Shot, an advanced digital drive system that allows operators to precisely zoom between pre-programmed focal
