MK3.x Motor
A powerful and quiet lens motor with
smooth performance. The brush-less vector-
drive gives unparalleled smoothness during
high-torque / slow-speed moves.
Warnings
The motor is a powerful device which is
capable of causing injury or damage.
• Never touch the drive gear when the
device is powered on.
• The motor is not to be used on
extremely stiff or damaged lenses.
• The motor requires no user
maintenance. Please note that
opening the motor can affect its
internal calibration and voids the warranty.
Variants – MK3 and MK3.1
The MK3.1 revision features a dual-sided hub (allowing the gear to be fitted to
either side, or both sides simultaneously). The gear train has also been further
improved, with improvements to efficiency and a further reduction in
operating noise level.
MK3 and MK3.1 models use identical firmwares and have identical compatibility.
Attaching to a rig
Affix the motor to the rods, but don't yet mesh the drive gear to the lens gear.
Rotate the focus ring so that it is not too close to either end stop. Now mesh
the gears, and plug the Digital Motor into the Receiver. The Digital Motor will
begin its Auto-Calibration Routine.
