Not sure if this is really a fair comparison since one is 45mm and the other is a 55mm, and I haven't tested them myself yet.

You can follow the link above to see some sample pictures from the Sony A7r with the Contax G 45mm f2 (the page is in Thai though so beware).

But according to one eager tester who also has an A7 on pre-order, the Contax F 45mm is sharper wide open at f2 than the Carl Zeiss FE 55mm f1.8 stopped down at f2. This has not yet been confirmed by other testers yet and you must also keep in mind that the 55mm was a copy that is being used for testing at a store so it is being handled by dozens of people everyday so it might not be the best copy around.

If this is true though I will certainly be rushing to ebay right now to get myself a copy of the Contax G since they are currently only selling for $300-$500 Dollars.
