Servo Control of Zoom Lenses, Application Examples

Wireless Lens Control System

Canon offers a new wireless control system as an alternative to the cumbersome control cabling that is often required between the lens controllers and the lens-camera system. This consists of a Transmitter Box (WB-10T) that is connected to the lens controllers, and a Receiver Box (WB-10R) that is mounted close to the lens. These two boxes can be separated by up to ten meters, and the wireless connection between them provides precisely the same degree and quality of controllability as afforded by the cabling system they replace.

Application Examples

Simple transfer between shoulder-mount shooting and tripod use

Easy construction of control system in difficult locations

Remote control within restricted areas

Simplifies control of lens-cameras on jib-arm or crane

System Configuration

*1 DC power supply for the WB-10T to be prepared by User. Size AA battery (x2pcs) is also available. *2 The Clamper and the Belt for the attachment are included as a standard component in the WB-10R.

User Interface

Along with continually

innovating optical performance, Canon strives to enhance the production experience, as evidenced with our

latest digital drive unit. Refined by long-term market research and worldwide experience, Canon mobilized the latest in 3D CAD-CAM design to significantly improve the human tactile interface to the control of zoom, iris, and focus. As a result, the digital drive unit features:

Optimized Ergonomic Design

The size and curvature size have been optimized to more comfortably fit in the palm of the operator's hand. Newly developed coatings improve the tactile interface between the user and the drive unit together with the new Rubber Grip Support.

Reduced Physical Stress

By reducing the width of the drive unit, the palm of the camera operator's hand is positioned closer to the optical axis, thus reducing the degree of arm bend which in turn lessens physical stress during prolonged shooting.

Improved Ease of Operation

The spacing between the focus ring and drive unit has been changed to avoid accidental interference with the drive unit while manipulating the focus control.
