An interview from the 2022 NAB Show in Las Vegas with Michael Burnham of Chrosziel. Chrosziel innovates, designs and builds the very best professional camera equipment and lens testing instrument solutions in the marketplace.

The Chrosziel CDM-PREM-FIZ Full Servo Drive Unit was developed exclusively with all three Fujinon Premista Lenses and is field installable. This compact and ergonomic design allows you to integrate the all-manual “cine style“ Fujinon Premista lens into your broadcast, multi-camera and remote head workflows in a very simple way, because you have all components in one housing.

Three perfectly positioned drive gears engage the Fujinon Premista lens with a high degree of precision, employing three powerful digital cine motors. The Chrosziel CDM-PREM-FIZ is particularly useful for cinematic multicam, ENG and OB work, where zoom and focus can be controlled from standard Fujinon TVstyle tripod controls or the handheld zoom rocker switch. It supports remote head and robotics applications via the Hirose 20pin Fujinon remote interface, which also allows the Chrozsiel Magnum wireless FIZ unit and all other compatible brands of FIZ to control the drive’s focus, zoom and iris.

The Zoomer is a compact and universal zoom motor that can be pivoted to almost any lens by simply mounting it on a 15mm rod. The universal motor unit CDM-UNI-Z2 fits seamlessly into the operating functions of the Sony cameras of the FX9 / FX6 / FS7 / FS5 series. The servo drive is controlled via the zoom rocker on the handle. The motor control can be addressed via Sony's camera-specific protocol and also works independently of the camera signals when a LANC zoom rocker is plugged directly into the servo.

Due to the included Chrosziel Flexi toothed ring (#206-30), the Zoomer can be used with almost any zoom lens even without toothing.

The multi-function handgrip, which in addition to the recording function and a zoom rocker also provide control over the camera menu and other freely selectable functions, are extremely popular on current video cameras with large sensors and are indispensable for effective operation.

The Chrosziel Universal Zoom Servo Drive now allows optimal use of all manual zoom lenses together with the multi-function handgrip. For this purpose, the Zoomer is slid onto a 15mm rod and swiveled onto the zoom lens. Two plug-in cables establish the connection with the camera. One cable is used for the power supply from the camera battery, the second for the connection to the control commands between the handle and the camera.

When using a standard LANC zoom rocker or handle with the Sony PXW-FS5, PXW-FS7 and PXW-FS7II, the servo is connected between the handle and the camera via an input and an output jack to receive all zoom control signals.
