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, a 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 hard carry case for the follow focus components.

Q: 3. Can you reverse the gear? Right now I turn the wheel away from me, and focus becomes closer. I'd like the opposite to happen....

A: It does not look like that is possible, but I would recommend mounting the follow focus upside down with a 15mm rod that is on top of the lens rather than on the bottom.

Q: 4. Is there a way to use this without a rig of any kind?
