Stopping down the 50mm to f/2 improves contrast, but introduce more optical

be...
What about an A50/2,8 macro, they are reasonably sharp wide open and seem to be
pretty abundant on the used market these days?
Interesting statement, can I just confirm that you are of the opinion
that the A50/2.8 is sharp wide open? I would have guessed that it
would be designed to work stopped down (*very* stopped down :-).
Any related comments on the K50/4 then?
Jostein, I can lend you both an A50/2.8 and a K50/4 if you want to
experiment (sorry I did not volunteer the FA50/1.7, I just use it too
often in the dark winter months). Let me know in private.
