The czoom is the zoom extension module of the lens control system. The complete zoom control unit consists of two components: the czoom and the chandle. Using the rosette, the unit can be attached directly to the pan-bar (using the cfast-czoom bracket), and through the CBUS connection to the camin, the user has full control of the zoom motor. The czoom can also be attached directly to the coperate (without the chandle ). In this configuration, three motors (focus, iris and zoom) can be controlled by one operator. The czoom can also be operated in hardwired stand-alone mode. This and many other features are what make the cmotion system a multi-functional, multi–user tool which can be controlled by various users, in both wireless or hardwired combinations, offering a modular and versatile solution to all your lens control needs.                        

 Example: the DP (or camera operator) has control of the zoom and the camera assistant, control of the focus.  The DP can attach the czoom to the pan-bar and hardwire it directly to the camin . This allows the assistant independent wireless control of the focus.  In a situation where the camera is mounted on a crane, the DP can connect the czoom to the chandle and then via the CBUS connector to the assistant's coperate for wireless control of the zoom from the ground.

• Ergonomic Design

As with all cmotion products, the chandle has been designed with ease of use and comfort in mind.  Crafted from wood, the chandle is very comfortable to hold, even for long periods.

• Motor Control with/without the camin

When using czoom connected to the camin , the user can control various manufacturers servo-motors (see camin ). However, through connecting a Y-cable, czoom can operate Arri CLM-1 motors independent to the camin. (Cable RZL-1, C019-KD1) is necessary for operation of the camera-Run function.              

• Speed Control

Movement of the zoom motor is controlled through a pressure sensitive Micro-Force joystick. The turning speed of the motor is controlled by the amount of pressure applied to the joystick by the user's thumb, in either a forward or backwards direction. For extra control, a maximum speed setting can also be applied. The ZAP (zoom as fast as possible) button assists in focusing and fast lens movements by over riding the speed control, and turning the motor at its maximum speed until the lens reaches its end stop, or the button is released.

• Function Lens

The rotation of the lens motors can be limited between two set values by simply using the LENS function. This operation electronically limits the lens motor movement between the user's two desired limits.  Rotation of the focus knob / iris slider remains unaltered.            

• Function ZAP

The ZAP (zoom as fast as possible) function allows the user to run the motor at its maximum speed in either direction. (see also Speed Control)        

• Mounting Capabilities

The czoom can be attached to various pan arms using cmotion's cfast-czoom
