They do not need a weaker one, they need an exact same one as with a bayer CFA. Optimal strength of AA filters has nothing to do with the CFA filter below it, only with the fact that details in the real world do not start and end on pixel borders.



Foveon sensors have the SAME aliasing problems as Bayer CFA sensors.

Foveon sensors have the SAME luminance moire problems as Bayer CFA sensors.

Foven sensors do not have the same chromatic moire problems as CFA sensors.



Manufacturers who use AA-filters do not do that to prevent chromatic moire problems, but to prevent the false detail to be recorded. That that also prevents chromatic moire effects is a bonus.



Moire patterns are considered very ugly, also from foveon sensors.

Aliasing is considered ugly too.



It is fine to make the choice to not use AA-filters (same as Leica does), but I do not like their bogus marketing speak nonsense,

Conceptually, they should have better chrominance resolution than classical Bayer sensors.

But I'd like to see a proof that it works in real life. For example MTF curves when shooting Red/Green/Blue test charts instead of black charts.
