Teradek RT Smartknob Wired Smart Controller

Teradek RT Smartknob Wired Smart Controller is a wired single-axis lens controller for off-camera focus or iris operation. From the supplied source, it works with MK3.1 receivers, Latitude lens controllers, RT lens motors, and compatible RED camera MDR systems.

The controller uses a main Smartknob for lens movement and includes a marking disk for visual reference. Six customizable buttons sit around the body, giving the operator quick access to functions such as control changes, recording start/stop, and other assigned commands.

Why It Helps

An off-camera lens controller gives the operator more freedom when the camera body is difficult to reach or when the control position needs to stay separate from the rig. The Smartknob can be mounted to a clamp or articulating arm and placed wherever it is most comfortable to operate.

The main knob provides direct control over one lens axis, while the marking disk gives the operator a clear place to note positions for repeatable moves. Its backlit design also helps keep those marks readable when the production is working in a dark studio, stage, or nighttime location.

The six customizable buttons reduce the need to reach for another controller during operation. Depending on the setup, they can change the unit’s function, trigger recording start/stop, or handle other assigned commands from the same control position.

Support for lens limits is useful when the operator needs to confine motor travel to a defined section of the focus or iris range. That can make short, repeatable moves easier to manage and helps prevent unnecessary movement beyond the required lens positions.
