About SmallRig Follow Focus F40 Kit

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.

• Newly designed silicone gear drives lens by friction without using follow focus ring
• Precise focus control and comfortable feel of damping
• Compact and portable, comes with a storage bag
• Different mounting positions; compatible with lenses of varying diameters
• Freely adjustable AB stops
• All-metal locking structure, safe and stable

SmallRig Follow Focus F40 Kit Features

  • Optimized S-shaped pattern for better anti-slip performance and a more visually striking look
  • Enhanced appearance with a more ergonomic design for easier damping adjustment
  • Removed handgrip for optional accessory purchase
  • Increased range of the rocker arm angle adjustment for greater flexibility
  • Improved T-shaped gear set for superior performance in high torque resistance and reduced backlash
