Teradek 's RT MK3.1 Brushless Lens Motor is designed to remotely control your lens focus, iris, or zoom, or other function. The MK3.1 motor operates smoothly and quietly, even during slow, high-torque moves. This brushless motor features electronic backlash-compensation, a high-resolution encoder, and an integrated heat sink. For optimal flexibility, a gear can be attached to either side of the MK3.1 Motor, expanding position choice to either side of the lens, depending on your camera configuration.

For maximum mounting flexibility, the MK3.1 Motor includes a height-adjustable 19mm rod bracket with a 15mm insert adapter. A 0.8 mod lens gear is included with the motor; gears are available separately in 0.4/0.5/0.6 mod, and 0.8 mod wide options. Thin, flexible 3mm cables (available separately) save space, and enable close arrangements of your motor(s) on your camera rig.
