The SmallRig F40 mini Follow Focus is a versatile manual follow focus system designed to attach to the left side of your lens. It offers precise and smooth focus control with its fluid focus knob and adjustable A/B hard stops. Mounting the follow focus is hassle-free, thanks to the included 15mm rod clamp with NATO rail.
