SmallRig Wireless Follow Focus Controller Kit 3917B

The SmallRig Wireless Follow Focus Controller Kit 3917B is a control unit for a wireless follow focus system, designed to improve shooting efficiency. Unlike the MagicFIZ Wireless Follow Focus Handgrip Kit 3782, it does not include the Wireless Receiver Motor. The handgrip features power-failure memory, eliminating the need for repeated lens calibration and AB point settings. It is equipped with an ultra-low-power 0.96" OLED screen and a vibration warning function for efficient user interaction. The ergonomic, modular design ensures comfort, with anti-twist 1/4''-20 holes on both sides for the handgrip adapter, making it suitable for both right and left-handed use. The kit is compatible with LP-E6 batteries for extended battery life, with the added benefit of powering the wireless receiver motor via USB-C cables and offering fast charging via an external adapter. The BLE module enables wireless REC start/stop, follow focus, and zoom control, which can also be achieved with control cables (ID: 3325, 2971, 2970) depending on the camera type, and works seamlessly with the Wireless Receiver Motor.
