The Teradek MDR.S is a compact, ultra-lightweight 3-axis lens control receiver designed for professional filmmakers who demand precision, portability, and reliability. Weighing just 2.4 oz and 30% smaller than its predecessor MDR.X, the MDR.S integrates seamlessly into any camera, drone, or gimbal setup without adding bulk. It supports up to three daisy-chained motors for focus, iris, and zoom control, and features FHSS wireless technology to eliminate interference, delivering a robust signal with up to 1.524 meters line-of-sight range. The onboard OLED display offers intuitive menu navigation, while the customizable external antenna enhances connectivity. With integrated Bluetooth, users can remotely configure lens maps and settings via the Teradek RT iOS app. The MDR.S also includes camera run/stop functionality for RED, ARRI, Sony, and LANC-compatible cameras, and supports lens data overlays on SmallHD monitors. Built from milled aluminum and engineered for durability, it operates in extreme temperatures and mounts easily via a ¼-20 thread. Compatible with Teradek RT controllers (CTRL.1, CTRL.3, CTRL.5) and motors (MOTR.S, MOTR.X, MK3.1), the MDR.S is the heart of Teradek’s wireless lens control ecosystem.
