Given the difference in brightness and contrast between the picture pairs,
all I can say is the camera's are very close, just as I would have expected.
And the main thing to be learned, as you already state, is that there is no
real noise penalty to be paid for the higher pixel count.
I haven't tried playing with the raw files myself though to match them more
closely, it wouldn't prove anything I want to know anyway
