Re: Dp3 Merrill Macro Focus Issues: Am I a dingus?

The first test I would run is to get a hard-cover book with a cover that has textual detail including a variety of sizes.  Possibly a box that is flat enough.  See how the text looks across the frame.  The closer you are to minimum focus the more likely you are to see soft corners/edges.  I know that my DP3M at minimal distance, which I do not use in real life, has soft corners at times.
