Nice report on this camera.
I agree the 20/1.7 is not as sharp as it could be but it is acceptable for the average user up to 30 meters in good light.
The Nikon 20/2.8 D does a much better job, as does the Olympus 50/2.0 Macro although this magnification is very high for most situations.
I have just bought a Nikon 28/3.5 AI and a Nikon 24/2.8 D second hand which I'll be trying out on the G1 and GF1 this week.  These are manual focus only of course.
