But alas it does not fit the 5D MkII.

Actually it looks like a complete toy compared to this:

This guy is doing it right and its very clear to see how it evolved far beyond the cool box to a fitted solution that is well connected, temperature controlled (to avoid condensation) and still allows easy access to the camera settings!

PS

Wish I could buy one!

I'm keen to see how they stack up against a camera such as the qhy9C.
Time to start the search for some pictures to use as a comparison.

I guess it would come down to the full well depth, Q/E of the chip and and its electronics. Once you have it cooled sufficently I imagine you have a significant gain.

Dying to see how your new camera will perform too!
