The Fujinon UA46X9.5BERD is a flagship-class 4K UHD broadcast zoom lens engineered for high-end studio production, outside broadcast (OB) trucks, and major sporting event coverage where extreme focal length reach and absolute optical performance are required. It is designed for 2/3-inch sensor broadcast cameras and provides a massive 46x optical zoom ratio, ranging from an ultra-wide 9.5mm to a super-telephoto 437mm. With its integrated 2x extender engaged, the focal length extends to an impressive 874mm, allowing for incredibly tight shots from great distances, such as capturing a player's expression from the opposite side of a stadium. The lens maintains a remarkably fast aperture throughout its range, from f/1.8 at the wide end to f/3.5 at full telephoto, ensuring excellent low-light performance and background separation even at extreme focal lengths.

Optical excellence is paramount in this lens, which is built to resolve the full detail of 4K UHD (3840x2160) and beyond. It incorporates multiple elements of Fujinon's proprietary Extra-Low Dispersion (ED) glass and Super ED glass to virtually eliminate chromatic aberration and ensure high contrast and color fidelity across the entire image field. A critical feature is the built-in Optical Image Stabilizer (OIS), which compensates for handheld shake, vibrations from mobile platforms, and wind-induced movement, delivering a stable, broadcast-ready image even at the longest focal lengths. The lens also includes a built-in 1/4 ND filter for exposure control and features an internal focusing system that keeps the front element stationary, which is essential for using matte boxes and polarizers.

The UA46X9.5BERD is equipped with a full digital servo system for smooth, precise control of zoom, focus, and iris. It is designed for integration into both manual and automated production environments, featuring compatibility with remote control panels (RCPs) and robotic camera systems through its extensive digital interface. The robust, weather-resistant construction ensures reliability in all shooting conditions. By combining an unparalleled zoom range with 4K optical resolution, advanced image stabilization, and professional broadcast features, this lens represents the pinnacle of Fujinon's optical engineering, providing camera operators and directors with the ultimate tool for capturing expansive wide shots and intimate, distant details in the highest possible quality.
