Thanks for the example. That X3 image is covered with aliasing artifacts. It may lack most color moire but it's full of luminance moire. The lack of an AA filter is one reason of many I've never seriously considered a Sigma camera and the example above shows why.

I find it mind-boggling that anyone would choose the image on the left over the Foveon.

Who said they would?  I'd prefer a standard Bayer sensor with a quality AA filter over the horrible crunchiness, jaggies, and false detail of the Foveon (or a Foveon with an AA filter).  The one on the left has either a lousy AA filter or no AA filter.
