The ARRI Anti-Twist 3/8″-16 Screw to 1/4″-20 Striped Rosette Mount Adapter from MID49 is designed to securely attach your Canon viewfinder clamp system to a mounting cage. The adapter features an ARRI anti-twist screw on one end and a 1/4″-20 striped rosette thread on the other, which is compatible with the Canon viewfinder clamp system. Additionally, three M4 threads on the side allow you to mount the microphone shockmount included with the Canon C400, C300 Mark II, C70, and other C-series cameras.
