See my Hasselblad X1D wish list.
This far-distance subject is one of the most demanding of any I know, because it is planar (flat) and with very fine detail. Any lens deviation such as symmetry or field curvature pops out instantly as a flaw. This is about as tough a real-world imaging challenge as there is.
This series from f/3.2 through f/16 demonstrates the awesome imaging power of the Hasselblad XCD 90mm f/3.2 at far distance.
Includes images from f/3.2 to f/16 at up to full resolution.
