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 DM-1X and DM-2 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 DM4X motor (right) is the smallest member of the family. It comes with an integral
bracket and is recommended for either light-weight video lenses or the zoom/iris rings of
small zoom or prime lenses.
