I'm told that no underwater 3D will ever work with a dome (to proper effect) because lenses focus on a curved virtual image. So you'll get a 3D effect.. but it will be of that virtual image.

It looks like a TM700 with a stereo optical splitter...recording two side by side half frames (left eye, right eye). I haven't been able to find many details about the system but I suspect it will only be half horizontal resolution ie the resolution of each image will be 960×1080 pixels.
It will certainly be more convenient for the average 3D shooter, but I think that a dual camera full resolution system is still the way to go for image quality and control over 3D parameters (eg convergence).

I have successfully built a 3D lens system with twin lenses behind a dome with proper effect. They do need to focus on the virtual image. The limitation is that there is a relationship between interoccular lens distance and dome diameter. When the lenses have a given IO, then the dome must have a given diameter. The math was worked out long ago and empirically tested by Dimitri Rebikoff. It's true the wide angle dome system that Imax built in the 80's didn't produce pleasing effects, but that doesn't mean it can't be done. My 3D dome lens takes really great wide angle close up 3D images...which was sort of a holly grail for me to achieve.

Mark -- I, for one, would like to know the details of the math, and see your images. Got any to share?
