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.
