Having compared the Sigma to a camera with a similarly-sized sensor, we here compare it to a similarly-priced, similarly targeted camera with a smaller sensor. The GRD III may have a wider lens (28mm equivalent, rather than the DP2's 40mm equivalent), but the compact body, fixed focal length design suggests a similar target market (if different individuals). And the difference in sensor size is immediately apparent, even at these low ISO settings.

Although, as we saw with the E-P1, the level of detail would look more similar if down-scaled but the GRD III simply isn't capturing as much detail as the DP2 in the first place - the fine text on the globe or the horizontal stripes on the medals on the third crop are clearly visible on the DP2 and no amount of down-sizing is going to bring it back on the GRD III.
