The Fujinon ZA12x4.5BERD, with focus and zoom servo, is a 4.5-54mm lens designed to provide 2/3" cameras with an ultra-angular to tele angle of view. The lens has a 12x zoom ratio and a 2x extender that doubles the focal range. Maximum aperture is f/1.8 at 4.5-41mm which is reduced to f/2.4 at 54mm. It has built-in digital servo for focus and zoom, which allows full control via RS-232.
Internal focusing minimizes the effects of lens breathing. QuickZoom improves zoom speed to 0.7sec end-to-end. With the push of a button, QuickZoom performs a quick shift to the tele end to check focus. When the button is released, the lens automatically returns to the previously set focal length. The FIND (Focused Intelligent Network Diagnosis) system assists in preventive maintenance and troubleshooting by evaluating electronic and mechanical parameters
