Fujinon ZA12x4.5BRM-M6 4.5-54mm f/1.8-2.4 ENG Style Lens with Servo Zoom, 12x Zoom Ratio & 2x Extender, 16-Bit Encoder

The Fujinon ZA12x4.5BRM-M6 ENG Style Lens with Servo Zoom is a 4.5-54mm lens, designed to provide 2/3" cameras with an ultra wide to telephoto angle-of-view. The lens has a 12x zoom ratio. The maximum aperture is a fast f/1.8 at 4.5-41mm and stops down to f/2.4 at 54mm. A digital servo for zoom control and a 16-bit encoder is also included.

Internal focusing minimizes the effects of lens breathing, which ensures a more consistent focal length when adjusting focus. Fujinon's QuickZoom technology 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. Finally, the Focused Intelligent Network Diagnosis (FIND) system aids in preventive maintenance and troubleshooting by evaluating various electronic and mechanical parameters.
