Abstract: A stereoscopic beam splitter having cameras with submersible lenses, such that the entire apparatus is filled with water when submerged. Submersible lenses designed to capture high-quality images underwater are utilized, allowing an underwater three-dimensional stereoscopic camera apparatuses to forgo a sealed housing with window port traditionally found in underwater stereoscopic beam splitter systems. The lack of a sealed housing and window port allows for drastically improved underwater image capturing performance and greater pressure caused by deeper water, in addition to making said apparatuses lighter and more compact.

Abstract: An underwater interchangeable lens mount system with a lens mount integrated within an underwater housing for a motion picture camera. The lens mount includes a first portion, a second portion and a third portion. The interchangeable lens mount is embedded in a watertight housing which provides more flexibility in using other types of lens mounts and avoids distortion in underwater photography due to a lens port. The interchangeable lens mount is designed to mount a submersible lens specifically designed for under water use. The interchangeable lens mount is adaptable to change with a wide variety of submersible lenses and acts as a camera's entire lens mount normally contained within a watertight housing. Two interchangeable lens mounts and two submersible lenses allow the motion picture cameras to make stereoscopic configurations.
