I am very excited by the anticipated release of the Sony S3CA box cameras, as they are reported to be gen-lockable. Just what that means remains to be seen, but hopefully it will be tri-level sync. Although they are probably overpriced for what they are (Sony A7SII sensor in a small box), they will be much more affordable than the Canon full frame box cameras are at $20,000. The UW 3D potential is great! Is anyone else tracking these? Is anyone else still interested in UW 3D?
