CamRIG is a set of tools for 3D artists. CamRIG comes in 3 different camera rigs: a simple tripod with bank control, a crane rig and an inversed target camera rig. I first made them for 3ds Max, and you can now use them in Maya! They are designed to work the exact same way as in max. Check the video to learn more or simply go to the download page
to get them.
