May or may not be true, but I have read several places that diffraction does occur much sooner in this 40MP camera. So after 5.6 apparently there can be issues.

Diffraction does not occur "much sooner" on a higher MP sensor. Diffraction comes on at the same rate and in the same magnitude, regardless of sensor resolution.

Some convince themselves otherwise by doing side-by-side comparisons of so-called 100% crops from cameras with different sensor resolution. They might compare, for example, 1000 x 1000 pixel regions of both...

... forgetting that they are looking "more closely" at a smaller section of the image from the higher resolution sensor.

If you were to make two prints of the same size from two images shot with the two cameras — one lower sensor resolution than the other — they would have precisely the same amount of diffraction blur.

Absent your showing with two images as indicated in your last paragraph - not prints of course, but online images - I am not convinced that you're right. But I would love to see the proof. With a Fujifilm 24 MP a d a Fujifilm 40 MP, that is. Thx.
