i'd like to see a 2.8 Ziess vs 2.8 P/L comparison (don't give a hoot about DoF/Bokeh) just like to see the sharpness.

Can't give you sample images but here are the sharpness figures as provided by LensRentals with the Pany 20/1.7 thrown in for additional comparison (MTF-50 for unsharpened output from RAW files, line pairs per image height, center/average):

2.0 760/620

2.8 890/670

4.0 940/750

Panasonic 25/1.4 on Olympus E-M5 (16 MP)

1.4 690/590
