The goal is to maintain DOF and field of view; if you crop to the same field of view, and the entrance pupils are the same size, then you have the same DOF.
100mm at f/32 is the same as 50mm at f/8 only if you don't crop 50mm by 2x.
These are both excellent lenses, and at f/32 and f/16, optical quality basically ceases to matter.
