With broadcasting technology rapidly converting to digital, Fujinon has developed a new digital servo control system, DIGI POWER, to enhance the performance of its zoom lenses. State-of-the-art components including a 32-bit RISC processor in the lens, a CPU in each servo demand, optical encoders and high-speed serial communication devices, together with the newly developed digital control circuit, provide 13-bit accuracy in zoom and focus control as well as a variety of new functions.An RS232 connector in the lens provides a connection between the lens and a PC, or other control device, for external control. This function has made it possible to control the lens functions with the high degree of accuracy and reliability needed for virtual studio and other robotic applications, and to raise the level for all production environments.
Digital Quick Zoom
Quick Zoom speed is improved to 0.7 seconds end to end. Quick Zoom provides for a rapid zoom movement to the telephoto position to check focus with the simple push of a button. Releasing the button returns the lens to the previously selected zoom position. Quick Zoom can now be performed remotely from the ERD-T22 and ERD-10A-D01. No other lenses come close in performance or features.
Digital Find System
The Focused Intelligent Network Diagnosis system aids in preventive maintenance and troubleshooting by evaluating various lenses’ electronic and mechanical parameters. This data may be stored for future reference in determining the need for service or adjustments.
