new DM4 Lens Motor<br />
The DM4 is a new micro-sized motor from Preston Cinema<br />
Systems. It’s made specifically for driving lightweight lenses<br />
where size and weight are critical, such as Steadicam and 3D rigs.<br />
The DM4 has been tested on Cooke 5/i and S4/i lenses. The DM4<br />
is not recommended for lenses whose barrels feel stiff, and you<br />
should not force the motor gear against the lens.<br />
In order to prevent wear and to maintain its precision, the motor<br />
uses polished metal gears coated with super-hard diamond-like<br />
carbon to minimize wear.<br />
The integral motor bracket, with an adjustable rosette gear, makes<br />
it easy to position the motor in tight places.<br />
The DM4 is compatible with Preston’s Motor Driver MDR-2,<br />
<strong>Digital</strong> Micro Force, and the single channel Video Lens Control<br />
units. (prestoncinema.com)<br />

All in the family: Astrid, Howard and Max Preston. As Tony Richmond, ASC, BSC<br />
famously said, “Nepotism is fine as long as you keep it in the family.” Max flew<br />

in Japan.<br />
