The diffraction from a 12mm lens at f/16 will be exactly the same as the diffraction from any other lens at f/16. Really, I know we were unable to convince you of this, but it\'s a fact.
The wavelength of light is in the nanometers. You can fit a thousand or so wavelengths across a 0.75mm aperture.
Yes you can fit many wavelengths through a .75mm aperture ... and you can fit more than 4X as many wavelengths through an aperture that is more than 2X as wide. The proximity of opposing/adjacent edges are closer to each other, wave amplitude will be stronger at closer intersections than at more distant ones. Think about two boats passing each other more closely vs. farther apart. The rise/fall of the intersecting wave amplitude will be more pronounced for the wake of the two boats that are closer together than those originating farther apart.
But, as you say ... I know I\'m unable to convince you of this.
