I just avoid mentioning it, but as you have asked.... this is the best image
I got with a fixed 50mm lens (I didn't test the 50/1.4 at F4 or below), it
is...

Even better than the famous 50/2 macro at F4 (and this macro is like new):

May be the 50/3.5 at F5.6 come close:

BTW, I found most fixed Zuiko reach its max performance at 2 stops from max
aperture. Further stop down does not improve much.
