This aperture series look at performance from very close range to far distance from f/4 through f/13. Depth of field is the limitation on total detail.
Anyone shooting medium format is presumably seeking top quality and thus ought to be thinking in terms of focus stacking, at least for near-far scenes like this. That’s because depth of field is in short supply. Stopping down too far degrades brilliance and depth of field too often remains inadequate even at f/16—a dulled image from diffraction that is still not fully sharp near to far.
