Have you tried f stops wider than f16? I suspect you're getting a lot of diffraction sharpness losses, since your effective f stop is far higher (worse) than f 16, due to magnification.

Yes, it's a dof tradeoff. That's why so many macro/micro photographers use stacking to get sharper pictures.

(sorry phil, meant to go to the OP. Wrong reply button. }

For the first photo I used a microscope lens that has a fixed aperture, and the images were taken at low resolution (6MP), just for fun.
The salt cubes obtained in the process are very small and irregular, ~0.15-0.25mm wide on the side of the cube.
