Fujinon ERD-20A-A02
Digital Servo Control: Provides smooth, precise, and repeatable zoom control, superior to older analog systems.
Wide Compatibility: Compatible with many Fujinon 2/3 inch HD/UHD Broadcast lens series that feature electronic servo control capability (especially ENG/EFP lenses).
Quick Swap: Modular design allows for quick and easy attachment and detachment from the lens, letting the operator switch between servo and manual control.
Ergonomic Handgrip: Provides a comfortable grip and a sensitive Zoom Rocker switch, allowing for tactile speed control.
Standard Connectivity: Typically includes a 20-pin connector port to plug into the lens and a port for remote Focus/Iris control (often connecting to ZSD-300D and FSD-5/8/10 units).
Description
1. Zoom Precision and Speed:
- The ERD-20A-A02 controller utilizes advanced digital servo motors, allowing you to precisely set minimum and maximum zoom speeds. This is critical for executing zoom maneuvers ranging from slow, subtle creeping zooms to fast, sharp crash zooms.
2. Optimal Mechanical Design:
- The controller is attached to the lens using a secure locking mechanism, ensuring no unwanted vibration or displacement during use. The handle is ergonomically designed to minimize operator fatigue during long shooting hours.
3. Control System Integration:
- Preset Functionality: Modern servo controllers like the ERD-20A typically have the ability to set and recall specific zoom positions (Presets), a necessary feature in studios and live programs.
- Expandability: The ERD-20A is part of the Fujinon control ecosystem, capable of operating alongside other focus and iris controllers via the lens’s connection system.
4. Ease of Repair and Replacement:
- As it is a separate module, the controller can be easily replaced or repaired without needing to send the entire lens in, minimizing downtime.
