From a very credible source:

"Diffraction thus sets a fundamental resolution limit that is independent of the number of megapixels, or the size of the film format. It depends only on the f-number of your lens, and on the wavelength of light being imaged. "

Mr Ichiro Kitao, I support the call to upgrade the FZ50.
I will not only buy one but two no questions asked...

Mechanism of light diffraction is not different from diffraction explained in aero and hydro dynamics.

Ultimately, diffraction depends on hole dia and thickness of the diaphragma petals. Now, presume that thickness of the petals has reached the limits (can't be done thinner), and try thinking again.

Looking for equilibrium...
