Chrosziel CDM-LWZ3-Z Zoom Servo Drive

The CDM-LWZ3-Z is designed for the Zeiss Lightweight Zoom LWZ 21-100mm/T2.9-3.9 T zoom lens (Zeiss LWZ.3). With the Zoom Servo Drive, Chrosziel addresses camera operators working in the broadcast, documentary and related sectors. Offering a reasonably priced device, the CDM-LWZ3-Z enables a creative process that may be impossible to achieve while pulling zoom manually.

The Zoom Servo Drive adds only indispensable weight to the setup. It contains one digital servo motor, the gear and a PCB with CPU in one single housing. The mounting of the Zoom Servo Drive makes the operator's workflow comfortable, with just three captive screws needed to mount it onto the Zeiss Lightweight Zoom.

The CDM-LWZ3-Z Chrosziel is able to unify both functionalities into one single unit. Supported are the smart grips of the Sony PXW-FS5 and Sony PXW-FS7 or any LANC compatible zoom rocker.

For operation, the power cable is connected and the two Jack cables with the handgrip and the camera. Once powered, the zoom servo drive calibrates automatically to the end stops of the lens. Zooming gently slows down the movement of the lens at the end stops.

By using a LANC device, you can build your own setup, like shoulder, Steadicam or Gimbal applications. The CDM-LWZ3-Z makes an all-day companion for the Zeiss  Lightweight Zoom LWZ.3 21-100 mm/T2.9-3.9 T zoom lens (ZEISS LWZ.3) and gives you creative freedom.

Single Unit Mounted Onto Lens

Three captive screws keep the single servo drive unit permanently fixed onto the lens.

Controlled via Sony FS and LANC Handgrip

The Sony FS5/FS7 handgrip zoom rocker directly controls the servo drive unit. Other zoom rockers with LANC protocol are compatible too, e.g. mounted to handgrip.

Camera Control Signals Forwarded

Control commands are immediately looped through to the camera (e.g. menu / user buttons / focus magnification / camera run and stop).

Four Zoom Servo Drive Zoom Modes

For freedom of creativity, you can choose between four different zoom modes: EB / Documentary Mode, Live / Hardcut Mode, Silent, and Direct Mode.
