Canon has introduced its CJ20ex7.8B, a 2/3-inch portable 4K zoom lens for professional broadcast, offering a 20x zoom ratio and focal-length range from 7.8mm to 156mm.

First shown as a prototype at IBC2015 in Amsterdam, the new lens enables the creation of high-resolution 4K video content. Adding to Canon’s 4K broadcast lens range for cameras employing 2/3-inch sensors, the new lens will join the CJ12ex4.3B, a 2/-inch” portable 4K zoom lens with the world’s widest focal length, the company claims.

Through optimal lens positioning and precise component assembly, the CJ20ex7.8B achieves 4K resolution images from the centre to the peripheral areas of the image field.

The new CJ20ex7.8B includes a built-in 2x extender, which even when shooting at the 312mm telephoto-end focal length, delivers an optical performance to support use with 4K broadcast cameras.
