Quote:Bayer sensors get detail (luminance) from all 3 CFA colours, so the difference is not that big. How did you come up with the 27-30mp figures?
 

Well, there's a bit of debate about the effective resolution from a bayer sensor. 

It also depends on the specific sensor. Most work with 4x4 layouts, but Fuji has 6x6.

 

Honestly I don't dare to make a statement myself but I have seen figures around the 67-75% mark of the nominal value (ok, thus 26-29mp to match the 19mp Foveon).

 

29mp is also the figure from Sigma for their interpolated images (only god knows why they do that because the RAWs are 19.6mp on the APS-C model).
