M43 is starting diffraction at F5.6 let alone 1" let alone 2/3" let alone 1:1.7" so tiny 1:2.3" pinhead sensors will be deep in there at F6.3 - good details can still be had as its easier to make really sharp lenses for small sensors . the glass must be amazing for the range they cover.

When I ran the numbers, I had the newer Olympus micro four thirds hitting the diffraction limit at f/3.7:

Physics people, please tell me how I am misapplying the Rayleigh Criterion

Did I do the math right?  I used the spacing between green photosites (4.75um) on a later model OM-D, and 530nm as the wavelength of green light.
