The Fujinon HK4.7x18-FA is a flagship cinema zoom lens from Fujinon's Premier "Hollywood" series, engineered specifically for high-end film and television production using large-format sensors, including Full Frame and Vista Vision. With a focal length range of 18-85mm and a remarkably fast constant T2 aperture, it is designed as a versatile workhorse lens capable of handling a wide array of shooting scenarios, from expansive wide shots to intimate close-ups, while maintaining a shallow depth of field and excellent low-light performance. The optical design incorporates advanced coatings and precision-ground glass elements to deliver images with exceptional sharpness, contrast, and color fidelity while rigorously controlling distortion, chromatic aberration, and flare. Its "FA" designation indicates full frame coverage, providing an image circle of 46.5mm to fully illuminate sensors up to 46.31mm diagonal.

This lens is built to meet the exacting demands of professional cinematography, featuring a robust, all-metal PL mount housing with integrated industry-standard 0.8-module gears on the focus, zoom, and iris rings for seamless compatibility with follow focus systems, lens motors, and matte boxes. The focus rotation is a generous 300 degrees, allowing for incredibly precise and repeatable focus pulls. The lens is parfocal, meaning focus remains stable throughout the zoom range, and features minimal focus breathing—critical for maintaining compositional integrity during focus changes. While it is a manual lens, it is engineered to interface with wireless control systems, as the focus and zoom rings are designed to be driven by high-torque servos for remote operation.

The HK4.7x18-FA is part of a calibrated, color-matched series, ensuring consistent optical performance across a set of lenses for multi-camera productions. Its construction prioritizes durability and smooth mechanical operation under demanding shooting conditions. Offering a compelling combination of a wide zoom ratio, a fast T2 aperture, full-frame coverage, and cinema-specific ergonomics, this lens is a premier choice for directors of photography and camera operators working on feature films, high-end television series, and commercials where optical excellence, creative flexibility, and reliable performance are non-negotiable.
