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. See also:
