If at f/18 there’s a soft shadows spot (several) but none at f/5.6 then I’m wondering about sensors.

Seems to be a common situation.

Never had that issue with film.  ;-)

Refraction is a big problem for pixel peepers, not so much for the rest of
us.
We never saw it as a problem on film because we weren't blowing things up
to 4x6 feet and then inspecting the image from 4 inches.

Those were the days, eh? When all we had to worry about was the Scheimpflug principle. How we skipped and jumped and laughed!

Anyway, that diffraction thing is easily solved if you ask me - just develop a sensor which only captures light when it’s behaving as a particle, then there’d be no diffraction.
