Cannon ZSD-300D Zoom Control & Cannon FFC-200 Focus Control

The Canon rear lens control bundle is a comprehensive, professional-grade solution designed for camera operators utilizing Canon ENG/EFP (Electronic News Gathering / Electronic Field Production) broadcast lenses. By relocating zoom and focus adjustments to the pan handles of a tripod, this kit allows operators to maintain complete, hands-on control over the camera's framing and sharpness without needing to touch the lens barrel directly.  This ergonomic configuration is an industry standard for live event coverage, sports broadcasting, and studio television production, where fluid tracking and instantaneous adjustments are critical.

The system relies on four distinct components working in tandem to provide uncompromised servo zoom and manual focus capabilities. The ZSD-300D Digital Zoom Demand electronically drives the lens's servo motor for smooth, variable-speed zooming.  For focusing, the FFM-100 Focus Module mounts directly to the lens's focus gear and physically connects to the FFC-200 Manual Focus Controller via a flexible mechanical cable.  As the operator turns the knob on the FFC-200 handle, the rotation is mechanically transferred through the cable to the FFM-100, delivering precise, zero-latency manual focus control.
