Canon KJ20x8.5B KRSD 20x HD Camera Lens

As HD camera equipment continues to spread to all facets of professional video production, Canon has been expanding its HDgc lineup of cost-effective lenses for advanced professionals. To help meet this increasing demand for affordable high-quality HD ENG lenses, Canon is proud to introduce the KJ20x8.2B KRSD, achieving outstanding optical performance with a light weight of 1.25 kg and wider-angle focal length of 8.2mm. Offering excellent operational mobility and outstanding optical performance, the KJ20x8.2B KRSD is ideal for wedding, corporate, and educational videographers, and will also play a vital role in broadcast news productions, which require an exacting level of performance. The KJ20x8.2B KRSD will help maximize your talents and deliver high-caliber production value to your projects.

Features:

• 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.
• Newly Developed Advanced Drive Unit
  Another advantage is quiet servo-operation, thanks to its optimum servo-motor construction, which also achieves faster zoom speed. This lens has been engineered (using 3D-CAD simulation) to eliminate servo-motor noise issues, enabling cameramen to zoom quickly and quietly to capture the moment. The lens also features Canon's renowned ergonomically-designed Drive Unit to offer an easy-to-grip, operator-friendly use.
  Also convenient is Shuttle Shot (see right page), a function which enables camera operators to pre-store zoom positions for instant recall on demand. Simple by design,* Shuttle Shot makes camera operation more reliable, supporting pinpoint zooming and ease of repetition.
