Not taking QE into consideration that means that every pixel on the D700 would be receiving 18.67x more light!! I have taken a wild stab in the dark but with an ~10 year increase in technology the QE may be light 0.4 vs 0.6 or a 50% increase. This brings the overall system closer to 12.4x increase in detected light per pixel.

Makes sense, Thanks Colin.
