The Canon YJ20x8.5BIRS is a 20x 2/3 inch lens built to offer high performance in SDTV news gathering and field productions. Lightweight and durable, the lens weighs less than 4 lbs and can be relied upon under harsh conditions. Additionally, the YJ20x8.5BIRS is equipped with features such as quiet servo operation and shuttle-shot programmable positioning.
Internal Focus for Ultimate Versatility Canon internal focus is made for the highest quality professional video cameras used in news and event videography. The front lens element is stationary and can be used with a matte box for greater lens flare protection, as well as a wide array of square and rectangular filters. Benefits include reduction in chromatic distortions, as well as decreases in flare.
Shuttle-Shot Technology The lens has an added capability for zooming; using the shuttle shot-switch. At the touch of a button, the lens can move to and from a pre-programmed point. This can be used both creatively, and as a no-hassle way of verifying focus.
Integral 2x Extender For instant close-up shots, the lens has a switch which inserts an element that doubles the focal length at any point in the zoom range. Instead of using the zoom function, the extender gives immediate close-up images.
