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.

Hey Rick,

I followed out your idea for a test using two hardcover books I had lying around with good textured covers.

For note, I am not using any macro/close up lens filters and am only using a tripod with a built in spirit level. This test was done with each book flat against a wall.

Here at the righthand corners and bottom left corner.

And here at each corner as well.

From your own personal experience, the constant presence of soft corners may unfortunately be the case with my Merrill as well.
