The ZA22x7.6BERD-S with Servo for Focus and Zoom is a 7.6-167mm lens, designed to provide 2/3" cameras with a wide to telephoto angle-of-view. The lens has a zoom ratio of 22x, and a 2x extender effectively doubles the focal range. The maximum aperture is a fast f/1.8 at 7.6-120mm and stops down to f/2.5 at 167mm. The lens also includes a digital servo for focus and zoom, which enables full studio control via RS-232.
Innerfocus minimizes the effects of lens breathing, which ensures a more consistent angle-of-view when making focus adjustments. QuickZoom improves zoom speed to 0.7 seconds end to end. With the push of a button, QuickZoom facilitates a rapid shift to the telephoto end to check focus. Releasing the button automatically returns the lens to the previously selected focal length. The Focused Intelligent Network Diagnosis (FIND) system aids in preventive maintenance and troubleshooting by evaluating electronic and mechanical parameters.
