Philips LDK5 Television Camera, lens mounting arrangement.

The front of the camera with the two 12 pin "Belling Lee" connectors.
Between the connectors are the two splined mechanical drive connectors. These link to the rear sides of the camera for direct connection of the lens controls to the lens. To the right is the control that locks the lens into position.

The filter wheel is visible, slightly misaligned from it's correct position.
