SmallRig mini Follow Focus F40 3010C, with exquisite and compact design, aims at providing precise and quick focus control for video shooting. It is made of new materials for optimized zoom control and features an anti-sweat, anti-slip focus knob (inspired by sports car hub) to feel comfortable. In the box, there is Rod Clamp (with NATO rail) 3011, which can be easily locked to the side or the top of most cages via a 1/4"-20 screw to allow reversing the focus action; a lightweight Silicone Gear (3852), which, when working with the M0.8-43T gear, drives lens through friction, without applying a follow focus ring, shortening your rig list and simplifying installation; and an all-metal 15mm rod clamp with jib, which has improved rotation angle to support different lenses. Adjusting A/B stops helps quickly set a focus length you desire. Besides, a storage case is included for more convenience and portability.Designers: Victor Tang & Peiwen He 1.Newly designed silicone gear drives lens by friction without using follow focus ring2.Precise focus control and comfortable feel of damping3.Compact and portable, comes with a storage bag4.Different mounting positions; compatible with lenses of varying diameters5.Freely adjustable AB stops6.All-metal locking structure, safe and stableNote:1.The silicone gear is M0.8-43T compatible only.2.To avoid gear slippage, please ensure the silicone gear fits tightly with the lens ring, particularly for large-damping zoom lens.3.The silicone gear only supports SLR / mirrorless lens.
