Rear Rod Adapter (CION, 15mm Studio) attaches to the two 1/4-20 holes at the bottom rear of AJA CION camera to provide 15mm studio spaced rear rod support. Great for holding a second set of rear rods without obstructing access to the integrated camera shoulder pad. Please note that this is the lesser common 15mm studio standard (100mm center to center distance). If you need 15mm lightweight spaced rods, see Rear Rod Adapter (CION, 15mm LW).
