The EMI 2001 Broadcast studio camera was an early, very successful British made Plumbicon studio camera that included the lens within the body of the camera. Four 30mm tubes allowed one tube to be dedicated solely to producing a relatively high resolution monochrome signal, with the other three tubes providing red, green and blue signals. Even though semiconductors were used in most of the camera, the highly sensitive head amplifiers still used thermionic valves in the first generation of the design.

Integrating the lens within the body of the camera had both positive and negative effects. On the positive side, it meant the optical nodal point of the camera was close to the centre of gravity, which could make operation easier and more instinctive when used on movable camera mounts such as pedestals. The downside was that lens manufacturers were limited to which lenses they could adapt to fit to the camera. This made the 2001 less attractive for outside broadcasts.

The 2001 was both heavy and large. The pull-out handles at each corner needed four people to safely move the camera with the lens in place. It also required a separate remote camera control unit and the cable connecting the two was over 2 inches thick. The standard servo controlled studio zoom lens had a 5 to 50 degree horizontal angle of view, with a minimum focus distance of either 36 inches (J type) or 18 inches (K type)
