This lightweight rod adapter offers 15mm LWS standards to the Compact Bridge lates CBP-1 (19mm) and CBP-2 (15mm) baseplates for ALEXA Mini/ Mini LF. Lens motors, follow focus units and other accessories attached to the 15mm LWS rods are solidary to the camera and won't be disturbed by the balance adjustments of the bridge plate. It attaches to the RMB-3 attachement points on the Compact Bridge Plate. Please note that the 15mm LWS adapter might have to be removed if frequent transitions from tripod to stabilizer unit are planned. Single 19mm rods can be attached to Rod Mounting Bracket RMB-3 for that effect.
