Outstanding Optical Performance
The KJ20x8.2B KRSD produces innovative performance with Canon's superb optical technology, Extraordinary Dispersion Glass (which is used in Canon's state-of-the-art Field/Studio box-type lenses), and other unique optical materials and coatings. Chromatic aberration is suppressed across the entire lens surface, enabling sharp images with minimal distortion at any object distance. An optimal balance of resolution and contrast in peripheral areas of the image enables you to realize sharp and clear pictures. Canon's unique Multilayer optical coatings will effectively reduce ghost and flares from the sun, headlights, or other bright light sources.
