The Fujinon HAc18x7.6-F is a high-performance broadcast and cine-style zoom lens engineered for Super 35mm and large sensor cameras, offering a versatile focal length range from a wide 7.6mm to a telephoto 137mm. It is designed to deliver the optical characteristics and operational features demanded by both high-end cinema production and modern electronic news gathering (ENG). With a remarkably fast constant aperture of T1.9 across the entire zoom range, this lens excels in low-light conditions and provides cinematographers with exceptional control over depth of field, enabling a cinematic, shallow-focus look even at wider focal lengths. The lens incorporates advanced optical coatings and precise glass elements to minimize chromatic aberration, distortion, and flare, producing images with high contrast, accurate color fidelity, and beautiful out-of-focus bokeh.

The "HAc" designation indicates it belongs to Fujinon's premier line of box-style lenses, featuring a robust, modular construction suitable for shoulder-mount camcorders or studio configurations. It is equipped with three independent, high-torque servo drives for zoom, focus, and iris, which are compatible with standard broadcast-style servo control units and can be operated with smooth, repeatable precision. The lens also provides full manual control with hard stops on the focus and iris rings, which are precisely geared for use with follow focus systems. A built-in 2x extender doubles the telephoto reach to 274mm, albeit with a corresponding light loss, adding significant versatility for capturing distant subjects. The optical design is parfocal, meaning focus remains consistent throughout the zoom range, a critical feature for professional video operators.

Built to withstand the rigors of field and studio use, the HAc18x7.6-F features a durable, all-metal housing. Its modular design allows it to be configured with various accessory options, such as manual servo grips or remote control panels. The lens supports extensive metadata output, including focus distance and zoom position, for integration with virtual production and VFX workflows. Offering a compelling blend of cinematic speed (T1.9), a wide zoom range, broadcast reliability, and cine-style operational features, this lens serves as a powerful, all-in-one optical tool for documentary filmmakers, drama producers, and broadcasters working with large sensor cameras.
