About the Fujinon UA23x7.6BERD 4K UHD 7.6-175mm f/1.8-2.4 ENG Zoom Lens, 23x Zoom
The Fujinon UA23x7.6BERD is a premium 4K UHD broadcast lens engineered for next-generation, large-sensor box-style and shoulder-mount cameras used in high-end Electronic News Gathering (ENG), documentary, and studio production. It is designed to cover the full 4K Ultra High Definition (UHD) resolution standard, resolving over 8 million pixels with exceptional edge-to-edge sharpness and minimal chromatic aberration, meeting the rigorous demands of modern high-resolution acquisition. The lens offers a versatile 23x zoom ratio, starting from an ultra-wide 7.6mm focal length for capturing expansive scenes and pulling back to 175mm for tight, detailed telephoto shots. This range, combined with a fast maximum aperture of f/1.8 at the wide end and f/2.4 at telephoto, provides outstanding low-light performance and shallow depth-of-field capability, crucial for achieving a cinematic look in field production.
A cornerstone of this lens is its advanced optical and mechanical design. It incorporates Fujinon's proprietary electronic servo system, offering smooth, precise control over zoom, focus, and iris. The "BERD" suffix indicates it features a built-in 2x extender (doubling the maximum focal length to 350mm), Optical Image Stabilization (OIS) to counteract handheld shake and low-frequency vibrations, and a built-in 1/4 ND filter for exposure control in bright conditions. The lens utilizes a sophisticated internal focusing system, ensuring the front element does not rotate—a benefit for using matte boxes and polarizing filters—and maintains constant physical length throughout the zoom range. The integrated servo grips provide ergonomic, responsive control, while the lens is also fully compatible with remote control units (RCUs) and robotic camera systems via its extensive digital interface.
Built to withstand the rigors of professional field use, the UA23x7.6BERD features robust weather-resistant construction. It employs Extra-Low Dispersion (ED) glass and advanced multi-layer coatings to suppress flare and ghosting while delivering high contrast and accurate color rendition. The lens is designed for cameras with a 2/3-inch optical format, utilizing a B4 bayonet mount for secure attachment. With its combination of 4K optical performance, extensive focal range, fast aperture, and integrated professional features like the extender, stabilizer, and ND filter, this Fujinon lens represents a comprehensive optical solution for broadcasters and content creators who require the highest level of image quality and operational flexibility in demanding production environments.
