The F40 mini Follow Focus from SmallRig is an adjustable, manual follow focus that mounts to the left side of your lens. It features a fluid focus knob that ensures smooth focus control and precision with its adjustable A/B hard stops and is easily mounted using the included 15mm rod clamp with NATO rail. It also includes a 3.9″ 15mm rod, an 0.8 MOD/43T gear, and an adjustable, belt-style focus gear ring.
The anti-slip and anti-sweat focus knob prevents moisture build-up and provides comfortable dampening control. The belt-style lens gear ring wraps around the lens, and different-size gear rings with different gear teeth measurements may be utilized. A replaceable marking ring is included in the package, as well as a carry bag for the follow focus components.
