Ironic though, that those "landscape photographers" stop down to get "everything sharp", and then incur so much diffraction softening that the higher resolution sensor is kinda useless ... The high res. sensors are of benefit for those who shoot with relatively large apertures... Street photographers, portraits and so on.

It might be ironic in certain ways, however having more pixels to play with is without a doubt a great bonus.

And that those "landscape photographers" drag along tripods, making the compactness of mirrorless a bit pointless.

Compactness is not just for portability. With a compact camera (even dragging along a tripod) is still more portable than a bulky FF camera plus a strong tripod.
