The camera mounts onto this formfitting aluminum cage with an integrated 1 4 -20 screw, and it incorporates an anti-twist design with padding on the base to protect the camera from scratching. It maintains access to the camera s controls and hot shoe, and it features a variety of mounting options. In addition to one integrated shoe mount and multiple 1 4 -20 and 3 8 -16 accessory threads, the cage features ARRI-style accessory threads for preventing accessories from twisting when mounted on the cage. The cage also features a NATO rail on the side and mounting threads on the front for a separately available lens adapter. An Allen wrench stores on the bottom via a magnet for tightening the camera screw.
