Like it or not, the only affordable solution to shooting close to those settings today is the GoPro Hero 3 Black.
It is astounding that the ML crew has been able to unlock as much as they have from the Canon CMOS sensor and its firmware, but even without an electronics or programming degree, the present specifications of the Canon sensors (and just a mere explanation of their operation) makes their limitations quite understandable.
The fact that these gentlemen have squeezed dual-ISO out of these sensors is fascinating in its own right.
