SmallRig 4745 Follow Focus F50

Precise Focus Control for Video Production

The SmallRig 4745 Follow Focus F50 is designed to give filmmakers smooth, accurate focus control on set. Its adjustable drive-gap system helps eliminate backlash, delivering a more reliable and responsive focusing experience.

A one-touch, stepless damping lever lets you fine-tune resistance from 0.3 kgf to 1.0 kgf, so you can match the feel to different lenses and shooting styles. With 2-step A/B stop switching and 360° quick push-pull zoom support, this follow focus adds flexibility to a wide range of workflows.

Flexible, Modular Design

Included with the system is a silicone gear ring that supports friction-based focusing on mirrorless lenses, plus a compact silicone handwheel for a comfortable, non-slip grip and precise adjustment. The unit mounts via a Φ15mm rod and a single rod clamp, allowing placement on the left or top side of the lens with adjustable angles for versatile rig setups.

Whether you are shooting handheld or on a tripod, the modular construction makes setup fast and dependable.
