Through optimal lens positioning and precise component assembly, the CJ20ex7.8B achieves high-quality 4K resolution images from the centre to the peripheral areas of the image field. Delivering superior colour reproduction, the lens allows professionals to create compelling ultra-high resolution video.
The new CJ20ex7.8B includes a built-in 2x extender, which even when shooting at the 312mm telephoto-end focal length, delivers superior optical performance to support use with 4K broadcast cameras.
Featuring a compact, lightweight body design, the lens delivers exceptional mobility in response to the needs of the broadcast industry, facilitating shoulder-mounted shooting and convenient transport.
