Overview
Key Features
Widely Compatible Lenses: SmallRig Wireless Follow Focus Kit (Lite) 4296 is designed to provide a precise and low-latency focusing experience for video shooting. It is compatible with a wide range of cinema and zoom lenses with high damping, such as CP. 3 35mm for ZEISS, Arles 50 / 75mm F1.4 FF / VV for DZOFilm, CN-R35 T1.5 L F for Canon, FE C 16 - 35mm T3.1 G for Sony lens, etc
Peak Torque of 4.3 kgf.cm: The receiver motor adopts a variable speed gear set design, which can provide a high torque output of 4.3 kgf.cm. Compared with the previous generation product, the torque peak is increased by more than 2 times, and the response efficiency is increased by 35%, making it easy to drive the zoom lens
Up to 21H Battery Life: The handwheel is equipped with a built-in 1400mAh battery and adopts smart sleep tech for long-lasting power, which can provide about 21h of ultra long battery life. The Receiver Motor supports a wide voltage input range of 5V-18V, compatible with PD and QC fast charging protocols. Please use the provided power cord or a USB 3.0 cable to avoid insufficient torque issues
User-Friendly Design: The wireless follow focus kit uses two light colors, red and blue, to indicate the connection status and channel (blue light-F00-1; green light-F15-1), and provides intuitive operation instructions. The control is simple and efficient, making it easy for beginners to get started
One-Click Lens Calibration: The Handwheel supports one click A/B dotting, and you can adjust the appropriate A/B focal length according to your shooting needs. The kit features a memory storage function, eliminating the need to recalibrate lens travel and AB point settings in case of power loss, enhancing shooting efficiency

👎 Cons
- Receiver motor requires an external power source rather than running on its own battery
- Designed for high-damping cinema lenses — may deliver imprecise control on lightweight still photography lenses
- Limited to two preset channels, which may be restrictive in multi-unit wireless environments
- Only two selectable wireless channels limits use in multi-unit setups on the same set
- 15 fps video output at the handwheel is not suitable for demanding cinema capture work
- Does not include a focus gear ring — lenses without built-in gear teeth require a separate accessory
- Color-coded channel system is limited to two channels, which could be restrictive in multi-operator setups
- Must use the included cable or USB 3.0 to avoid insufficient torque, limiting cable flexibility
- Lite version may lack advanced features found in higher-end wireless follow focus systems
- Requires a USB 3.0 or included cable specifically — lower-spec cables can result in insufficient torque
- Lightweight photo lenses with minimal damping may not pair well with the motor's torque output
- Receiver motor requires an external power source rather than running on its own battery
- Designed for high-damping cinema lenses and may not pair well with lightweight photo lenses
- Requires USB 3.0 or the included cable specifically — lower-spec USB cables may cause torque issues
- No integrated focus distance markings or display on the handwheel for numerical reference
- Only two channel options may be limiting on sets running multiple wireless focus units simultaneously
