Abstract
An underwater camera has a frame assembly, which has a frame and front and rear covers mounted on the frame. The frame has a viewfinder tunnel. A pressure housing has an internal cavity holding the frame assembly. The pressure housing has opposed first and second viewports. The viewports each bear directly on the viewfinder tunnel and are disposed in non-load-bearing relation to said covers.
