The UA13x4.5BERD 4K UHD Wide ENG 13x Zoom from Fujinon is a 4.5-59mm lens designed to provide 4K+ compatible images. This lens has a 13x zoom ratio, and its integrated 2x extender effectively doubles the focal range to 9-118mm. Image distortions are suppressed even at the ultra-wide 4.5mm focal length, and its high-resolution imaging remains consistent to the periphery of the frame. An internal focus design minimizes the effects of lens breathing and a handheld-style focus/zoom servo is included. The nine-blade rounded iris helps produce natural-looking "bokeh" (out-of-focus highlights). The UA13x4.5BERD incorporates 16-bit encoders for compatibility with virtual systems and its QuickZoom feature enables a one-push zoom-in for focus checking.
