It seems the 5D3 beats the D800 (and the 5D2) in it's anti-aliasing. You'll notice the 5D3 image is just about perfect, the 5D2, D800 and the A900 all show problems, phantom vertical or horizontal lines that seem to cut through the pattern. Red arrows show the problem areas.
The image is from DPR's RAW image comparisons. It's not quite visible on the D800 at the reduced resolution on this site, however if you download the image you should be able to see it clearer at full size.
You can also go to DPR's page here and move the selected area to the pinwheel directly below the + in the center of the frame. You can of course compare how other cameras perform against the 5D3 on this same test.
