A viewing module is releasably connected to the pivotable member to extend rearwardly along the side of the camera and has a CRT facing rearwardly with an eyepiece for viewing the CRT. The viewing module has controls for the CRT on an outwardly facing surface for manually adjusting the controls. Cooperating and releasable electrical connectors are provided between the pivot member and the viewing module for transmitting video signals and electrical power therebetween. An extension member, either of a fixed length or telescoping, may be installed between the pivot member and the viewing module and has the same electrical connectors.Other References
