Canon has introduced the newest member in its HDgc series of portable HD zoom lenses. The new KJ20x8.2B IRSD portable HD lens is specifically designed to support low-cost image acquisition systems for a wide range of applications and users, from broadcast ENG to professional freelance HD shooters.
Top of the list of the new lens features is its built-in 2x extender, an imaging option previously seen only on higher-end HD lenses. As a result, the KJ20x8.2B IRSD offers ENG shooters and other camera operators improved subject framing flexibility, claims the company.
At 8.2mm, the new KJ20x8.2B IRSD is also Canons widest lens in the 20x zoom class, and it covers various focal lengths, particularly when combined with its built-in 2x extender expanding its 8.2mm-164mm focal length to 16.4mm-328mm.
The performance of Canons new KJ20x8.2B IRSD portable HD lens is the result of the companys design tools, including optical simulation and 3D design technologies, optical glass materials and coatings and dispersion glass.
.The lens has minimised axial and lateral chromatic aberrations, coma aberrations and geometric distortion. The new optical materials and multi-layer optical coatings used in the lens effectively lessen the ghosting, flare and veiling glare that might be stimulated by strong light sources – sun in the daytime and car headlights at night time.
