 Only Marconi with their small neat Mk VIII and the cameras from Link (a few years later) followed the concept.Most camera manufacturers claimed that a format where the lens protrudes out in front of the camera gave greater choice of lens supplier and, of course, it was a format that made life easier for camera designers, so the enthusiasm of cameramen for the integral zoom concept was found to have little long term influence on camera designers.Even EMI abandoned the notion of having an integral zoom lens, with its new camera, the Type 2005, which had a format reminiscent of the very earliest Philip’s experimental camera (with its three horizontally configured tubes)

The circuitry in the 2001 was all solid state apart from the pick-up tubes and, in the early cameras, the first stage of the head amplifiers.
