The Fujinon XA55X9.5BESM 9.5-525mm EFP Box Lensis a high zoom ratio lens that lends itself to covering sporting events and other large-scale productions. Its 55x zoom range can extend from normal to super-telephoto focal lengths. The 2x Extender doubles your focal length to achieve tighter framing on your subject.

The box housing is specially designed to prevent fogging of the lens elements during changes in temperature or humidity allowing the lens to be used outdoors in inclement weather conditions. In addition to being weather sealed, this lens is secured against dust and other small particles that might harm the lens.

Since the lens incorporates Fujinon's DigiPower Digital Servo technology, it can provide precise, repeatable digital control from studio paint boxes, PC's, and traditional analog controls. Digipower also permits setting custom speeds for zoom and focus, zoom limiting, and other servo parameters. Diagnostics and advanced controls can also be accessed via an RS-232 port.

Q: 5. How does this mount to the lens itself? Is there a mounting point on all Fujinon ENG lenses specifically for this?

A: There has been a mounting point on the under side of every Fujinon EGN lens that I have come across. You simply align the gear teeth with the corresponding teeth on the focus ring of the lens, while aligning the small guide post with the hole in the under side of the lens. The thumb screw should then screw into the proper hole and hold it in place. Once that is done, you attach the manual focus control on your tripod arm to the unit and you're all set.
