FAQs:
What does the SmallRig Wireless Follow Focus Kit do?
This system allows users to adjust lens focus wirelessly using a handheld controller. The handwheel sends signals to the focus motor mounted on the lens gear, rotating the focus ring remotely. This setup allows an operator or focus puller to control focus precisely while the camera is on a tripod, gimbal, or moving rig.
How strong is the focus motor, and what lenses can it drive?
The motor produces approximately 0.4 Nm of torque, which is sufficient for most mirrorless and DSLR lenses as well as many lightweight cinema lenses. This level of torque allows the motor to drive both focus and zoom rings smoothly without stalling. It is particularly suitable for compact camera rigs where larger cinema motors would add unnecessary weight.
What is the wireless operating range of the system?
The follow focus system can operate wirelessly at distances up to around 100 metres in open environments. This range allows a focus puller to control the lens from a distance during studio setups, gimbal work, or remote camera positions. Transmission latency is extremely low, typically between 0.03 and 0.07 ms, helping maintain responsive focus adjustments.
How is the system mounted onto a camera rig?
The motor mounts to a standard 15 mm rod using the included rod clamp. A quick-release follow focus ring attaches to the lens gear, allowing the motor to drive the lens smoothly. The clamp also incorporates a NATO rail for fast attachment to compatible rig components, making installation quick when building or adjusting camera setups.
How is the handwheel powered and charged?
The controller includes a built-in 1400 mAh rechargeable battery that lasts up to 21 hours on a full charge. Charging occurs via a USB-C port and supports both PD and QC fast-charging protocols. The motor is also powered through USB-C, allowing flexible power options when building a rig.
