Well, I have to disagree completely with the "this is a lens test" argument. Testing lenses assumes as a fundamental prerequisite that everything else must be equal; on the contrary, there couldn't be a less equal lens testing ground than this different crop, different sensor technology, different RAW converters. If there is something that my comparison is NOT, is a lens comparison. In fact, this is intended a systems comparison more than anything else; to do so, I chose the best, highest-res DSLR in my possess (the D800E) and choose to compare its output with the best Foven DSLR (the SD1 Merrill); to make the comparison meaningful to photographers who need to choose one or the other for real world work, I equipped each with lenses covering the same field of view. There actually is no way to compare these sensors "everything else being equal" because there isn't a common RAW converter (except for Iridient, for those inclined to use it), and because even equipping a Nikon or Canon crop camera with the same Sigma lens you'd use on the SD1, pixel count and pixel pitch would be different, etc.
All this comparison (and those that will follow) is meant to be is a showcase of what a photographer doing a particular kind of work can expect if he needs a fast lens covering (in this case) the 50mm's field of view on the best Bayer camera out there vs the best Foveon camera out there. Which one is better for his/her work, he can decide by him/herself by looking at the IQ results and by chechking out which features he or she needs in a camera.
IMHO working photographers, or at least myself, are more interested in things such as these; for one, I am purpose-driven, that is to say if I need to shoot something with a 50mm at a certain distance and under certain light, I want to see how different cameras render images in similar conditions and with lenses covering that particular field of view. Everything else, I leave to better reviewers than me and their shots of resolutions charts - they do a wonderful job, and there are plenty of such tests around already
