The ARRI Mini Base Plate MBP-3 Set for Canon 5D MKII has been designed to fit the camera through a dedicated adapter plate. Natively designed for 15 mm lightweight support rods, the MBP-3 is compatible with the ubiquitous ARRI Bridge Plate BP-8/9 for studio setups. Most cameras supported by the MBP-3 are compatible with the ARRI Cage System I.
