This is a camera rig I developed for my own short film. It was inspired by several rigs. I used the features I liked the most from various cameras and combined it into one super rig.
If you rename the .ma file to JoshCam.mel, you can save it in your scripts folder and use the following line of MEL code to import the camera into your scene with the click of a button!
file -import -type "mayaAscii" -options "v=0;" -pr "JoshCam.mel";
