Marconi MkVIII Television Camera Varotal 30 lens

A range of zoom lenses can be fitted to the Mk8 with various zoom angles and range extenders. From a compact 10:1 f2.9 lens to a big 42:1 lens by Angenieux.

The focus control is a mechanical drive to the lens through a two-speed gearbox. The zoom control is a conventional servo system with zoom demand control and an optional shot box. Iris control is servo operated from the CCU front panel or the engineer's iris & lift control panel in the normal way.

At the rear of the lens is a X2 range extender switch.
