Introducing the Smallrig 3010D Mini Follow Focus F40

The Mini Follow Focus F40 Smallrig 3010D is a compact manual follow focus for controlling focus from the left side of the lens.

It mounts using the 15mm and is operated with the short rod provided. The system drives the focus ring via a 0.8 MOD/43T and an adjustable toothed lens ring. This configuration is suitable for rigs where the operator or camera assistant needs to maintain accessible focus control without adding a bulky module.

The Smallrig 3010D Mini Follow Focus F40 features adjustable A/B stops. These allow you to limit the travel between two focus distances, useful for repeating a focus rack without going beyond the markings. The marking ring is replaceable, making it easy to change shots or lens configurations.

The focus knob is designed with an anti-slip and sweat-resistant surface to minimize slippage due to hand moisture. The strap-type silicone ring tightens around the lens, and the system accepts gear rings of varying sizes and tooth counts when adapting to other compatible lenses.
