With the exception of a very slightly different tone curve, it's clear that the two cameras are producing essentially the same image with indistinguishable levels of detail. The hints of moiré seen in the JPEG comparisons of these two cameras suggested both have very light anti-aliasing filters, this test suggests they're very similar indeed.
