Here is a custom Maya camera I’ve made for our fulldome productions. Just import and go! (Requires Domemaster3D)

maya scene (using mental ray) – custom fulldome camera rig

Notes
— Uses an aim/up to point the camera. It is applied in a way that allows you to aim the camera and not worry about the camera Z rolling within 180° field of view.
— A hemicube camera rig is parented within fisheye camera (and hidden). Therefore it automatically uses the aim. So if you need to switch over and use hemicube cam for whatever reason, then it’s there and waiting for ya!
— Includes a dome visualization that isn’t selectable. It just lets you know where the camera is facing. It’s also helpful as a guide to see where the springline hits in a scene. I called it the “FYI”.
— Click the camera to see the custom attributes: FYI scale, FYI visibility, FYI Uni Helper, Cam Locator Scale, and Custom Roll. Includes the ability to scale the camera locator without affecting the cam scaleXYZ. (Since changing cam scaleXYZ changes how textures are placed onto surfaces.)
— Preset Domemaster3D settings. (This assumes you already have Domemaster3D installed). Check out this simple tutorial to apply the DomeAFL lens shader to a Maya camera.
— It’s by no means perfect and definitely has a gimbal-lock-camera-flip if you go past 180°, but it works well if you know its limits. Play around with it and you will quickly understand.
