Studio cameras are light and small enough to be taken off the pedestal and the lens changed to a smaller size to be used handheld on a camera operator's shoulder, but they still have no recorder of their own and are cable-bound. Cameras can also be mounted on a tripod, a dolly or a crane, thus making the cameras much more versatile than previous generations of studio cameras. These cameras have a tally light, a small signal-lamp used that indicates, for the benefit of those being filmed as well as the camera operator, that the camera is 'live' – i.e. its signal is being used for the 'main program' at that moment.
