Are you using a magnifying lens on the front of your DP3M?

Maybe the image would be more evenly focused with one of these on the front? Just a thought.

Sorry I could not find the spec for filter thread for the DP3M, not even on Sigma USA. But, you could buy an adapter ring to use the above 58mm lens set. There are quite a few similar lens sets available at B&H.

I used to have a DP3M but never used it for macro.

I second this - I didn't look up the minimum focus distance on the DP3 - 8.9". So they did leave out the details of how they were getting the macros.

@OP - any additional lensing elements added to your lens will result in poor performance like this, especially magnifying elements. Even flat, simple UV filters can mess with clarity.
