The Ratworks Sony Venice Rialto Cage System is a full cage that is able to remain on the extension block without having to be completely disassembled in order to install the lens mount.
The bottom, top and each side can be installed singularly to suit complex and constrained rigging scenarios. The cage is narrow enough to fit into most major remote heads. The cage also features two Arri Standard Rosettes on the side ribs for attaching hand held bars. Sensor plane markings on the cage offer convience for focus pullers.
