The outstanding optical performance of Canon's KJ20x8.2B portable HD lens is the result of Canon's world-leading design tools, including cutting-edge optical-simulation and 3D-design technologies, novel optical glass materials and coatings, and extraordinary dispersion glass. Collectively these technologies and materials have facilitated an unusually high degree of optimization of the cost-performance ratio of the KJ20x8.2B. The lens has minimized axial and lateral chromatic aberrations, coma aberrations, and geometric distortion. The optical materials and multi-layer optical coatings used for the KJ20x8.2B effectively attenuate optical artifacts such as ghosting, flare, and veiling glare that might be stimulated by strong light sources (for example, sun in daytime and car headlights at nighttime). The KJ20x8.2B exhibits a high MTF (modulation transfer function) at picture center that is also well controlled out to picture extremities. This high MTF is well sustained even with operational adjustments of focal length and object distance. The KJ20x8.2B's optical performance is well-balanced for both near and distant subjects, and its rendering of distant subjects at wide angles – frequently required for landscape and cityscape shots – surpasses previously available lenses in this price range. The lens also features an enhanced macro function that effectively reduces the minimum object distance (from the front of the lens) to only 10mm.
