ABSTRACT:
A motion picture camera employs a mounting plate supported within the camera housing by means of sound-insulating connectors. All of the sounds-generating moving parts are supported solely on the mounting plate and all are out of contact with the camera housing. The lens, however, is mounted directly on the camera housing and is out of contact with the support plate and is thus prevented from radiating sound generated within the camera housing. An insulated double door assembly is mounted on the camera housing for access to the interior of the housing. Means accessible exteriorly of the outer door are provided for releasably locking the inner door with respect to the housing.
