My vote goes for the Pentax-F 50mm f1.7. It's an incredibly sharp lens.

To throw out something different here I'll say my SMC K 28mm 3.5 is the sharpest lens I have measuring edge to edge. I love, love love using this lens to create stitched panoramas. It comes out as one wide and incredibly sharp photo. The colors remind me of Kodachrome film which also reminds me that sharpness is only one factor.

Center sharpness, my FA 50/1.7. Needs to stop down to f/2.5 to get there, but from there on, it's definitely my sharpest in the centre. I does suffer veiling glare and requires stopping down to f/8 to get sharp edges though. Sharpest overall, from corner to corner with no noticeable defects, the DFA 100 macro. An amazing, flawless lens and pretty much as sharp as the FA 50/1.7 centrally too.

I got an A50/1.7. It's MUCH sharper from f/2 already. f/8 is amazing. I even put a reverse mount on the fifty to get razor sharp macro.

All the lenses I have had have been sharp 'enough' really (FA43, FA20-35, K85 and Voigtlander 90mm APO).

The DA14 is not pin sharp at long distances but extremely good at closer range (0.2m - 5m).

None are as sharp as the Sigma 24mm Super Wide f2.8 Macro on an SD15, or the sharpness king that is my Sigma DP3m..........

I have been using the DFA100WR every day this month. These are all wide open. OK, maybe one is at f/3.2....
It is impressively sharp, and don't get me started with what it does from f/8-f/11
