Conundrum: Depth of Field vs Diffraction

The tradeoff between depth of field and diffraction is problematic on a huge sensor.

As discussed in Diffraction: Influence of Pixel Size, there is hard limit for depth of field when diffraction losses are taken into account. With ~4.8 micron pixels, the Hasselblad H6D-100C has the same pixel size as a Nikon D810, for which f/16 is an image quality disaster from diffraction losses*. Having the same pixel size as the Nikon D810, the Hasselblad H6D-100C does equally poorly at f/16 since the Airy Disc vs pixel size is the same. In other words, f/11 is the limit to stopping down on the Hasselblad H6D-100C without rapidly degrading the image, from diffraction.
