A pop up prism camera ( 10 ) having a pop up prism lens assembly ( 11 ). A first lens assembly ( 14 ), a second lens assembly ( 18 ), and a prism assembly ( 21 ) are moved in relationship to a camera housing ( 12 ) controlled by a cam tube ( 20 ). The prism assembly ( 21 ) projects outside the camera housing ( 12 ) when the pop up prism camera ( 10 ) is in an operational configuration. A prism ( 100 ) of the prism assembly ( 21 ) redirects an optical path ( 48 ). A non-angled portion ( 44 ) of a first cam groove ( 30 ) causes the prism assembly ( 21 ) to remain fixed relative to the camera housing ( 12 ) while continued rotation of the cam tube ( 20 ) allows the first lens assembly ( 14 ) and the second lens assembly ( 18 ) to continue to move to accomplish a lens zoom function.
