Rent NowThe SmallRig F40 mini Follow Focus is a lightweight, compact manual follow focus system designed to mount to the left side of a lens, bringing precise, repeatable focus control to video shooting without the bulk of a full-size follow focus unit. Elevating filmmaking precision, it’s a practical addition for camera operators who need fine manual focus adjustments on a rig.
The follow focus features a fluid focus knob delivering smooth, dampened control, paired with adjustable A/B hard stops to quickly set and repeat a desired focus range for pulls between two points. An adjustable, belt-style focus gear ring wraps around the lens barrel to interface with the unit’s included 0.8 MOD/43T gear, with interchangeable gears and gear rings available separately to accommodate different lens diameters. Mounting is handled via the included 15mm rod clamp with an integrated NATO rail, along with a short 3.9-inch (3.94″) 15mm rod for attaching to a standard camera rig.
Handling centers on an anti-slip, anti-sweat focus knob that prevents moisture buildup while providing comfortable, confident grip during extended use. A replaceable marking disk lets users note specific focus points directly on the unit for quick reference during a shoot.
Build quality uses an all-metal locking structure for safe, stable operation, combined with ABS and aluminum gear components. The unit measures approximately 4.7 x 3.4 x 2.4 in. (120.5 x 87 x 60mm) and weighs approximately 6.9 oz. (195g), and includes an Allen wrench for assembly along with a hard carrying case for organized storage and transport.
