All in all, it seems that this dispute successfully got itself into a deadlock. It would be really helpful to get some raw files both from Sigma and filter-less Bayer, unfortunately I can't find it online. Genotypewriter - you mentioned that you have a 50D with AA filter removed, would you mind sharing with some raw files please?

Here you can find a 5D without AA-filter and with AA-filter RAW file.

Again, regarding our discussion:



I do not claim ANYWHERE that a bayer CFA AA-filterless sensor will get the SAME results as a Sigma foveon withouth AA-filter.



I claim that extra "detail" from the foveon is mainly to do with the AA-filter lack, and that it mainly concerns false detail. And that detail is luminance based, and luminance data very successfully gets extracted from the bayer-CFA RAW data (as can very clearly be seen from the D200 examples).
