Diffraction series

I have shot a diffraction series today. 


P45+ Diffraction results

What this shows is the sharpness peaks at f/5.6. A significant drop occours at f/16.


The images below show difference in central sharpness a5 f/8 and f/22. Please not that a significant portion of the sharpness lost to diffraction can be regained by adequate sharpening, so stop down when needed, but for optimum results medium apertures are normally the best choice.
