ECC Tools The Binary DSLR Rig has it All & then Some:

ECC Tools has created The Binary Rig to give DSLR cameras the functionality and usability of a cinema camera. HDSLR cameras have the ability to capture beautiful cinematic images, but they lack features necessary to use the cameras reliably under the rigors of film production. The Binary Rig integrates the functionality that film industry professionals have come to expect, without sacrificing cost to the owner.

The Binary Rig is an open platform that supports most DSLR cameras, allowing the user to stay current to changing trends in digital cinematography. The cornerstone of The Binary Rig is its modular system that both addresses and conforms to industry hardware standards. Whether for run and gun or high end studio production work, the user has the option to customize and utilize whatever accessories deemed necessary the job.
