V. Digital Motors

The DM-1X is a high speed and high power motor. It is specifically recommended for

driving the focus ring of cinema lenses.

The DM-2 is a smaller and lighter weight motor. It is recommended for driving the zoom

and iris of all lenses, and the focus for all but very stiff lenses.

The DM4 motor (right) is the smallest member of the family. It’s recommended for either

light-weight video lenses or the zoom/iris rings of small zoom or prime lenses. The DM4

comes in two versions differing in the reduction ratio; the DM4A version has half the

speed, but twice the torque of the DM4

All motors are available with an integral bracket (the “A” version). This bracket provides for

simplified mounting and also allows the motors to be positioned very close to one another.

A rosette gear securely locks the swing arm in position.

The swing arm clamps to 19mm rods. Step-down bushings accommodate 15mm and 0.635”

rods, p/n 4320 and p/n 4321 respectively.
