Museum of the Broadcast Television Camera

The Marconi MkI (A) type TA.111302 has a Knob for the focus control.
The Marconi MkI (B) type TB.111302 has a version of the lever focus control, known as the "beer handle"
The MkI camera was made by Marconi in the UK but is closely based on the RCA TK30 camera.

The 4 lenses fit to the turret using a fine screw thread and a range of focal lengths were available together with external, individual, neutral density filters that could be used in bright conditions. No remote control of exposure was provided. On outside broadcasts this would be operationally very inconvenient!. The later Marconi MkII camera had iris motors fitted to each lens. I suspect that these were also retrofitted to the MkI's that the BBC had when they were used on OBs.
