High-Precision Cinema Calibration

The ARRI Follow Focus FF-5 Cine Base (K2.65246.0) is the foundational module designed for high-end cinematic lens control. Featuring an internal 2:1 gear ratio, this base unit slows down the drive gear relative to the focus knob rotation. This expanded rotational range grants focus pullers the delicate, high-resolution control required when pulling focus on wide-aperture cinema primes and zooms with expansive focus scales.

Complete Modular Expandability

Built to adapt to evolving rig configurations, the FF-5 Cine base features an open, modular mounting layout. The drive bridge accepts left- or right-hand standard knobs, hard-stop focus wheels, and specialized speed cranks. Furthermore, its adjustable gear positioning arm slides smoothly horizontally and vertically, allowing the unit to mate seamlessly with varying lens barrel diameters across different lens manufacturers.

Production-Ready Reliability

Manufactured out of heavy-duty materials, the FF-5 Cine base eliminates flex and mechanical play, ensuring every subtle adjustment translates directly to the drive gear. Designed for quick-turnaround production sets, it snaps or slides effortlessly into standard camera support rigs, providing camera crews with a solid, highly dependable platform for demanding film and television projects.
