Spanning the Film and ENG worlds, and supporting 4K production, the Fujinon ZK25-300mm T3.5 to T3.85 Cabrio Lens is a 12x zoom for Super35 single-sensor cameras, and it features a PL mount. The long zoom range allows you to shoot medium-wide to long shots without changing lenses, and it holds its maximum T3.5 aperture from 25 to 273mm, almost the entire length of the zoom, losing less than half a stop as it reaches 300mm. This minimized iris ramping makes it easier to use a continuous zoom along the entire zoom range of the lens.
