Product Description


SmallRig Wireless Follow Focus Controller Kit 3917

SmallRig Wireless Follow Focus Controller Kit 3917  is a control unit of wireless follow focus system. Compared to MagicFIZ Wireless Follow Focus Handgrip Kit 3782, it has no Wireless Receiver Motor. The handgrip has power-failure memory that spares you from repeated lens calibration and AB point settings, thus improving shooting efficiency. Its ultra-low-power 0.96" OLED screen and vibration warning function provide a simple but efficient user interaction experience. With an ergonomic and modular design, it feels comfortable and features anti-twist 1/4''-20 holes on both sides for the handgrip adapter, making it suitable for both the right hand and  left hand. It is compatible with LP-E6 batteries for longer battery life which can also power the wireless receiver motor via USB-C cables and with fast charging for charging LP-E6 batteries via an external adapter. The system’s BLE  module helps in wireless REC start/stop, follow focus, and zoom which can also be realized by control cables (ID: 3325, 2971, 2970, depending on your camera type) with Wireless Receiver Motor.


1. Wireless Receiver Motor and Electronic Controller Module can be operated only under the same frequency band and number.

2. Please check anomalies when there is a vibration warning from the Electronic Controller Module.

3. For instructions, please refer to the Wireless Follow Focus System User Manual.
