There is an article in this month's Modern Photography (June?) that
implies that each lens has an optimal sharpness f-stop. For instance,
if the lens ranged from f1.8 to f16, the optimal f-stop would be 2/3rds
of the way to f16, or about f5.6(?).

Other things that affect sharpness:
 - Another article compared 35mm with large format film. Obviously, the
   large format was sharper (for the price it better be!).
 - A tripod          \
 - Mirror lockup      |- these are pretty obvious though
 - Subject lighting  /
