When I viewed the photos on my 30 inch monitor I was surprised at how awful the cables looked in all photos but the Sigma produced them clearer.

Of course they look terrible with that much oversharpening of all the images combined with the hot air distortions.

Foveon has better per-pixel resolution due to its stacked design, it's not a secret. Sigma claims 2x resolution advantage, but it pays for it by using 3x photo-diodes, more noise, worse colors, bad dynamic range, prone to harsh clipping with color artifacts, much higher power consumption. Also as soon as you resize the output the resolution advantage is gone, it looks no different than any Bayer sensor. So far Sigma wasn't able to capitalize on the advantages of Foveon design, and its disadvantages are killing the prospects of it ever becoming a viable option for the majority of the photographers.
