FUJINON ZK4.7×19 is a standard zoom lens with a frequently-used focal length covering from 19 to 90mm.Thanks to the detachable servo drive unit on the ZK series, the lens can be operated in the same manner as a traditional broadcast ENG-Style lens and accessories. Furthermore, with the servo drive unit removed, traditional cinema manual, or external cine motors for zooming and focusing operation is also available for all models of this series. With the latest optical simulation technology and high precision large diameter aspherical elements, it has achieved both high optical performance and a lightweight compact body of 2.85kg.

*Q: What are the main differences between V1 and V2 of Cabrio 19-90mm? (source: Fujinon's website, 2023)
While both Versions of 19-90 have a 114mm outside front barrel diameter, V2 has a 111mm filter thread and V1 has a 112.5mm filter thread, resulting in a doubling of the housing thickness. This change was made due to the thinner front ring being more prone to damage. New version front barrels for V1 Cabrios are available from Fujifilm Optical Devices service centers at a charge. The serial number on V1 is also located on the front rings whereas the serial number on V2 is located on the zoom ring. When looking at the factory model number of Cabrio 19-90, V2 includes a “B” at the end (ZK4.7×19-SAFB). In terms of optics, lens performance is in many ways a matter of personal subjectivity. Some optical adjustments were made to improve Cabrio 19-90 V2; however, the differences in optical performance between the two versions can be difficult to perceive when looking at real-world moving pictures, as compared to high-end lens bench/test equipment.
