Considering Moore's Law photography data in gigapixels are only a matter of time - maybe even terapixels.

There are some considerable difficulties building a lens that can provide terapixels of information -- as opposed to noise -- in a single capture. The simplest one is diffraction.

Isn't diffraction already setting in at Apertures of 5.6 or 8 in a camera like the A7R4? If that is the case what happens with all the nice landscape optics where photographers shoot at F11 and over?
