The JVC Professional KJ20X8.2B IRSD is a high-performance 20x portable broadcast lens engineered for professional HD and 2/3-inch sensor cameras. This lens offers an extensive focal range, starting from a wide 8.2mm and extending to a telephoto 164mm (20x zoom), and includes a built-in 2x extender that doubles the focal length to 328mm, providing exceptional versatility for sports, wildlife, events, and news gathering. The integrated Optical Image Stabilization (OIS) system is crucial for achieving steady shots at long focal lengths, especially when shooting handheld or from unstable platforms. Its portable design and manageable weight make it suitable for both shoulder-mount camcorders and larger broadcast camera systems.

This lens is built to broadcast standards with robust construction and smooth, responsive controls. It features three independent servo rings for precise manual adjustment of zoom, focus, and iris, which can also be operated via servo motors for smooth, repeatable movements. The lens utilizes an internal focusing design, meaning the front element does not rotate, which is essential for using matte boxes and polarizing filters. The 2x extender is engaged via a switch, instantly doubling the reach without compromising the lens's relative aperture as significantly as a digital zoom would. Compatibility with standard 2/3-inch bayonet mounts ensures it can be used with a wide range of professional broadcast cameras.

The KJ20X8.2B IRSD is a versatile optical tool that provides cinematographers and broadcast engineers with the reach and stability needed to capture distant subjects with clarity. Its combination of wide zoom range, built-in extender, and image stabilization makes it a powerful choice for any production requiring flexibility and high optical performance in the field.
