The ultimate GH4 video rig! What is it...?

Is the Sony a7S ii not a viable choice as well? The battery life stinks and the AF is nothing to write home about but the footage is good. However, you'd still need an external recorder and housing for 4:2:2. Of course, I may have answered my own questions...

I have the Nauticam housing for my GH4 but with a 501 as an external monitor.

4:2:0 compression isn't a problem, however the a7S doesn't allow 10 bit internal recording where as the GH4 does...
