The Fujinon HA13x4.5BERM is a premium 2/3-inch broadcast studio lens renowned for its exceptional super-wide-angle capability combined with a versatile 13x optical zoom. Engineered for live production environments such as sports broadcasting, entertainment shows, and studio programming, this lens provides a focal length range starting at an extremely wide 4.5mm (equivalent to a horizontal angle of view of approximately 86.5 degrees on a 2/3-inch sensor) and extending to a telephoto 58.5mm. This range allows camera operators to capture expansive crowd shots, wide stage views, or tight close-ups from a single camera position without sacrificing image quality. The lens is parfocal and features a built-in 2x optical extender, effectively doubling the telephoto reach to 117mm when engaged, adding further flexibility for isolating distant subjects.

Optical performance is a hallmark of the HA13x4.5BERM, featuring Fujinon's advanced optical design with Super Extra-low Dispersion (Super-ED) glass elements to virtually eliminate chromatic aberration and ensure high resolution and contrast across the entire zoom range. Its fast maximum aperture of F1.7 at the wide end (F2.2 at telephoto) enables excellent performance in low-light studio conditions. The lens incorporates three high-torque servo drives for zoom, focus, and iris control, which are fully compatible with standard broadcast control panels and provide smooth, responsive operation essential for on-air use. The focus ring offers a generous 270-degree rotation with hard stops for precise manual control when used with a follow focus system.

Built to the rigorous standards of broadcast duty, the lens features a robust, all-metal housing and is designed for integration with broadcast camera systems from manufacturers like Sony, Ikegami, and Grass Valley. Its modular "B4" mount is standard for 2/3-inch bayonet-style cameras. The "BERM" suffix indicates specific features, which typically include a built-in optical image stabilizer for steady handheld or shaky pedestal shots, and an internal focus design that maintains a constant physical length during operation. The Fujinon HA13x4.5BERM is a critical tool for broadcasters who demand the creative flexibility of a super-wide angle, the reach of a long zoom, and the optical excellence required for high-definition and 4K production, all in a reliable, studio-ready package.
