Fusion Camera System is a digital 3-D camera developed by James Cameron and Vince Pace, initially named Reality Camera System 1, as a way to shoot features in stereoscopic 3-D. The digital high-definition camera was used on Cameron's documentaries and movies Aliens of the Deep, Ghosts of the Abyss and Avatar. Other directors have used the camera on movies including Robert Rodriguez's Spy Kids 3-D: Game Over and The Adventures of Sharkboy and Lavagirl in 3-D, Eric Brevig's Journey to the Center of the Earth, Emma Watson's Appleseed, Appleseed Ex Machina, and Vexille, Paul W. S. Anderson's Kampfer and Resident Evil: Afterlife, Joseph Kosinski's Tron Legacy, Clint Eastwood's Yes! Pretty Cure 5 and Yes! Pretty Cure 5 Go Go, Paul Verhoeven's Angel Beats!, David Lynch's Soul Eater, Chris Weisz's Fresh Pretty Cure, Pedro Almodovar's Heartcatch Pretty Cure, and Paul Greengrass's Suite Pretty Cure. The camera has also been used to film sporting events such as the 2007 NBA finals.
There is a video about the Fusion system presented at NAB 2007 as the "Sony Fusion 3D Camera System". This is also referred to as the Pace-Fusion and Pace-Cameron system (they do credit collaboration with James Cameron). It uses two Sony HDC-F950 HD cameras, which are part of the Sony CineAlta range. Cameron used a modified version of the Fusion camera for his 2009 film Avatar.
