ZOOM SERVO DRIVE FOR ZEISS LIGHTWEIGHT ZOOM LWZ3 21-100 MM – VERSION II

MOTORIZING YOUR ZEISS LWZ.3 ZOOM LENS WITH CDM-LWZ3-Z2



CONTROLLED VIA SONY FS & LANC HANDGRIP

Control directly the zoom servo drive via optically de-coupled LANC sockets and Sony FS5 / FS7 handgrip zoom rocker. 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 & stop).


SINGLE UNIT MOUNTED ONTO LENS
Three captive screws keeping the single servo drive unit permanently fixed onto lens.

4 ENHANCED ZOOM MODES
EB / Documentary, Live / Hardcut, Silent, and Direct Mode



Single unit mounted onto lens

The CDM-LWZ3-Z2 is designed for the Zeiss Lightweight Zoom LWZ 21-100 mm/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 enabling creative processes that may be impossible 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. Just three captive screws are needed to mount it onto the Zeiss Lightweight Zoom (LWZ.3).

  • Sony handgrip / other LANC handgrips with zoom rockers are working, too
  • Zoom Servo Drive CDM-LWZ.3-Z2 with 4 enhanced zoom modes
  • Zeiss Lightweight Zoom LWZ.3 21-100 mm/T2.9-3.9 T zoom lens (ZEISS LWZ.3)
  • Chrosziel Light Weight Support 401-FS5


Controlled via Sony smart grip or any other LANC hand grip

Until today, zoom servo drives were operated either by the inbuilt zoom rocker or external zoom devices. A second handgrip controls the camera settings or user commands. Both units are separated from each other and cannot be operated by one single hand.

With the CDM-LWZ3-Z2 Chrosziel was 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 the end stops of the lens. To further support the operator’s piece of mind Chrosziel implemented the so called “Soft Ramping”. Instead of having the zooming suddenly and unexpectedly stop, the zoom gently slows down the movement of the lens at the end stops.

By using a LANC device the operator may build his or her setup, like shoulder, Steadicam or Gimbal applications. Thus, the CDM-LWZ3-Z2 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 the camera operator the freedom of creativity needed.


All camera control signals are forwarded

Control commands (e.g. menu / user buttons / focus magnification / camera run & stop) are immediately looped through to the camera via the LANC protocol.
By using a Sony PXW-FS5 or a Sony PXW-FS7 camera with a SWIT battery a D-Tap to a (straight or angled) Lemo compatible 5-Pin power cable is used (Chrosziel order numbers: MN-AB-A with angled Lemo compatible socket / MN-AB with straight Lemo compatible socket). The two Jack-Jack cables are forwarding the control commands from the hand grip.
If e.g. a Panasonic Varicam, Sony PMW-F5 or Sony PMW-F55 are used a combined cable with power and start / stop is required, like a Hirose 4-Pin to a (straight or angled) Lemo compatible 5-Pin cable (Chrosziel order numbers: F55-A2-PCAM-A with angled Lemo socket / F55-A2-PCAM with straight Lemo compatible socket). Also, the two Jack-Jack cables are forwarding the control commands from the hand grip.
Also, Chrosziel offers a variety of power cables with straight and angled plugs for all types of camera power out sockets and batteries including camera run / stop functionality (see PDF for download).

  • LEMO compatible 0B 5-Pin socket (camera start / stop, power)
  • 2.5 mm Jack port (control command In / Out)
  • 3.5 mm Jack port (control command In / Out)
  • USB type mini A-B (firmware updates)


Take four: zoom servo drive zoom modes

For freedom of creativity the operator may choose from four different zoom modes: EB / Documentary Mode, Live / Hardcut Mode, Silent, and Direct Mode.

EB / Documentary Mode
Designed for long and smooth zoom drives with the CDM-LWZ3-Z2 it offers slow creeping zoom transitions while keeping the motive perfectly framed.

Silent Mode
To reduce the sound of the zoom servo drive the maximum speed of its motor is limited to 40 percent making the setup almost inaudible.

Live / Hardcut Mode
To catch the best moments, the Live / Hardcut Mode is useful. It uses 80 percent of the maximum speed capacity of the motor offering fast zoom drives but with Soft Ramping.

Direct Mode
The Direct Mode finally uses the full speed capacity of the Zoom Servo Drive. The LANC commands are implemented instantaneously without ramping and smooth transitions. Useful for B camera operators catching snaps shots from the concert.

How to switch zoom modes

You can choose the different modes by pressing the zoom rocker for round about 25 seconds, then the green LED flashes very fast while changing the zoom mode and after that it blinks 1, 2, 3 or 4 times* – depends on the zoom mode you chose (* 1 = EB / Documentary / 2 = Silent / 3 = Live / Hard Cut / 4 = Direct). To cycle through these all you need to do is hold the zoom rocker down one way for a couple of seconds to switch to the next mode, and the other way, hold to reverse.

Interview with Nino from cinema 5D:
What’s remarkable about the Chrosziel solution is its extremely small size and elegance, the quietness and simplicity of it. It also loops through the LANC information from a handgrip like on the FS7, meaning that you can use the zoom rocker on the handgrip as well as the start/stop or menu buttons. It’s self-calibrating as well. It’s clear that Chrosziel is on a mission to motorize the zoom lenses from all kinds of manufacturers, and we like how they are doing it.
