To level up the playing field, we've downsampled the E-P1's image to match the image height of the DP2 (we frame the scene vertically, so the DP2's extra pixels along the long axis are only being used to describe the white wall at the back of the scene). We used Photoshop's 'bicubic sharper' reduction method in order to compensate for the inherent softening effect of downsizing.
As you can see, the DP2's resolution is still marginally higher than that of the E-P1, but we're at the point where you have to be looking very close to see it. The E-P1's image has been rather over-sharpened by the resizing process but it's doing almost as good a job of capturing fine detail as the Sigma. The Olympus is one of the sharper 12MP cameras on the market but it demonstrates that there is only the smallest resolution advantage to the Sigma's Foveon sensor that is sampling all three colors at each point.
