This figure is very helpful to select the best camera for low light or astrophotography:

Thanks for doing this. It is indeed very helpful and I especially appreciate the exposure time graph. Clearly I'm way better off with the 5D3 instead of the 40D at prime focus This really is a clear illustration of the advancements made in sensor performance.

I must confess, I'm still unclear of the relationship between read noise, well depth and dynamic range. Will camera A, with half the read noise of camera B, at the same ISO and with the same well depth have one more stop of usable dynamic range?
