The problem is that at high ISOs, the DP2m shows significant banding and streaking... and in color, magenta and green streaks can show... especially if underexposed. Of course, you get lucky here and there with high ISO, but with other modern cameras, high ISO is almost fool proof (i.e. almost as easy as working with traditional low ISOs [asa]).
It's a wonderful camera if you use it within its boundaries. There is nothing like the detail from the Sigma at its size or at its price range.
