About Fujinon XA101X8.9BESM-TK

The Fujinon XA101X8.9BESM-TK 8.9-900mm f/1.7-4.7 2/3" Precision Focus Assist HD Lens features a combination of wide angle and 101x zoom range. Fujinon's Super EBC optical coating ensures superb optical quality and the exclusive anti-fogging design minimizes lens fogging and reduces downtime due to moisture.

Digi Power
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.

Fujinon's OS-TECH (Optical Stabilization) contains sensors to detect the slightest movement horizontally or vertically that could cause vibration. A correction signal is applied to the optical correction system, which helps to maintain a stable image while shooting from an unstable platform.

Precision Focus Lens
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 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.

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.
