The Fujinon HA22x7.3BERM-M6 7.3-161mm f/1.9-2.7 ENG Lens with Digi Power Servo Zoom is a 7.3-161mm lens, designed to provide 2/3" cameras with a wide to super telephoto angle-of-view. The lens has a 22x zoom ratio and a 2x extender effectively doubles the focal range. The maximum aperture is a fast f/1.9 at 7.3-113mm and stops down to f/2.7 at 161mm. The lens also includes a Digi Power Servo for zoom control, which facilitates semi-servo studio control.
Internal focusing minimizes the effects of lens breathing, which ensures a more consistent angle-of-view when making focus adjustments. With the push of a button, QuickZoom facilitates a rapid shift to the telephoto end of the lens to check focus. Releasing the button automatically returns the lens to the previously selected focal length.
Cruise Zoom allows the operator to start a zoom and then set the speed. This provides for a constant zoom speed without the possibility of inadvertently moving the zoom rocker. Zoom speeds as slow as 70 seconds, end to end may be achieved. The Focused Intelligent Network Diagnosis (FIND) system aids in preventive maintenance and troubleshooting by evaluating electronic and mechanical parameters. This data may be stored for future reference in determining the need for service or adjustments.
