The Fujinon XA77X9.5BESM is an exceptionally long-range, high-performance box-style studio/field lens engineered for 2/3-inch broadcast camera systems. With an extraordinary 77x optical zoom ratio, it covers a staggering focal length range from an ultra-wide 9.5mm to a super-telephoto 732mm, providing broadcasters with unprecedented flexibility in a single lens. This capability allows camera operators to capture everything from expansive wide shots of an entire stadium or arena to extremely tight close-ups of individual players or performers from a fixed camera position, making it indispensable for major sports broadcasting, large-scale event coverage, and wildlife documentary production. The lens maintains a constant maximum aperture of T2.2 across its entire zoom range, a remarkable engineering feat that ensures consistent exposure and depth of field control regardless of focal length, which is crucial for maintaining visual continuity in live productions.

The optical design incorporates Fujinon's latest technologies to deliver broadcast-grade image quality. It features a built-in 2x extender that doubles the maximum focal length to 1464mm while maintaining excellent sharpness, further extending its reach for extreme long-distance applications. The lens utilizes Fujinon's proprietary HBC (High Bandwidth Coating) to minimize ghosting and flare, and internal focusing mechanisms that ensure the front element does not rotate, making it fully compatible with matte boxes and polarization filters. It is equipped with three independent servo drives for zoom, focus, and iris control, all controllable via industry-standard protocols for seamless integration with broadcast camera bodies and remote control systems. The rugged, all-metal "box" construction is built to withstand the demanding environments of outside broadcast (OB) trucks and field production, featuring robust connectivity and heat-resistant design for continuous operation.

Designed for the most challenging professional broadcast scenarios, the XA77X9.5BESM includes advanced features such as optical image stabilization to combat camera shake at extreme focal lengths, a macro function for extreme close-up shooting, and an optical front extender. Its compatibility with large 2/3-inch broadcast sensors ensures low noise and high dynamic range performance. This lens represents the pinnacle of broadcast zoom lens technology, offering an unparalleled combination of reach, speed, optical performance, and durability for networks and production companies covering the world's largest and most demanding live events.
