Chrosziel announces its new Full Servo Drive Unit developed exclusively for the new Fujinon Premista lens series. The Servo Unit facilitates the large zoom cinema lens operation and thus, allows the privilege of using the Premistas in Run N’ Gun ENG shooting scenarios. Read its highlights below.

Premista Servo

Zoom cinema lenses are bulky and heavy and were designed for utilization in professional productions, rather than sole-operator situations. Thus, Servo units facilitate lens operation especially when shooting in uncontrolled environments, Run N’ Gun, documentary, limited budget, and small crews. Now, when the complete Fujinon Premista is ready for action, a servo solution is more than welcome.

As stated by Chrosziel: “This completely new, compact and ergonomic design allows you to integrate the ‘Cine Style’ Fujinon Premista lens into your ‘Broadcast’ workflow in a very simple way, because you have all components in one housing!”. The Servo Drive was developed for all three Premista lenses: 28-100mm/T2.9, 80-250mm/T2.9-3.5, and the newly announced 19-45mm/T2.9.
