This 1/4″-20 to Arri rosette attachment was designed specifically with the Panasonic GH Series and Sony a7/a9 Series of Tiltaing Camera Cages in mind, but is compatible with any cage that features 1/4″-20 threads.
It allows you to mount an Arri rosette attachment to your rig via two 1/4″-20 mounting screws.
The slot for the 1/4″-20 screws allows you easily adjust the attachment based on where the screw holes are located on the cage.
