ABSTRACT:
A snorkel camera system has a light-admitting opening at one end of a housing and the prime lens of a camera connected to the other end of the housing, and the housing is rotatably mounted on the prime lens such that the housing can be rotated about the camera to any desired position, the optical system being such that the image seen in the view-finder of the camera is maintained in the correct attitude regardless of the position to which the snorkel housing is rotated.
