The 4K UA14x4.5 Broadcast Servo Zoom Lens with S10 Drive from Fujinon is a 4.5 to 63mm zoom lens designed to support 4K origination and provide 2/3" cameras with an ultra-wide-to-telephoto angle of view. The lens has a 14x zoom ratio, and when you engage the built-in 2x extender, you double the focal length range. The lens features nine iris blades for a soft, natural bokeh, and it is designed to minimize flares and recreate true blacks.
The maximum aperture is a fast f/1.8 from 4.5 to 41mm and ramps to f/2.8 at 63mm. The lens features a digital servo for zoom control, and focus can be either manual- or servo-controlled. An internal focus mechanism minimizes the effects of lens breathing, which ensures a more consistent angle of view when making focus adjustments.
