Fujinon announced the 25-300 as the newest member of the Cabrio family right before this year's NAB show. The lens is designed for 4K Super 35 sensors and, with a 12x zoom ratio and constant aperture of T3.5 from 25-273mm, is definitely meant to compliment the rest of the Cabrio family.
At their NAB booth this year, Fujinon showed off the new lens, along with a mockup of the optional servo unit that will eventually offer electronic zoom, focus, and iris adjustment. Check out the video above for more details.
