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.
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.
Fujinon's exclusive Precision Focus Assist is now in the third generation and features improved focusing response, lower light loss, and reduced size. The PF system is the only focusing system that can maintain focus a any zoom position from the narrowest to the widest angle.
All new Fujinon lenses are compatible with the currently proposed 16:9 format. However, because of the various methods of achieving the 16:9 ratio, it is important to understand how the methods of ratio conversion are achieved.
There are two types of switchable-format cameras available today. One type uses 16:9-format CCDs and switches to the 4:3 aspect ratio. The other utilizes 4:3 CCDs and switches to the 16:9 format.
When the 16:9-format CCD system is employed, it is necessary to compensate for a loss in angle of view of about 20 percent that is incurred when switching to the 4:3 aspect ratio. To eliminate this problem, Fujinon offers an optional ratio converter that is located in a four-position extender turret in studio and field lenses, and in an enlarged extender housing in new hand-held lenses.
An additional option for lenses with an 82 mm filter thread (A18X7.6) is the lightweight front-mounted converter model RCV-82SC.
The Focused Intelligent Network Diagnosis system aids in preventive maintenance and troubleshooting by evaluating various lenses' electronic and mechanical parameters.
