Having got my Lumix GF3 I discovered it is possible to fix many 'legacy' Olympus and Nikon lenses to it. So I ordered adapters from Fotodiox in the US (via Amazon marketplace) and when I got back from Istanbul they were waiting for me. Test shots taken so far: 

 Olympus OM 28mm

 Nikkor 24mm

 Nikkor 50mm

Nikon E series 28mm

These were not all take at the same time so the lighting is a bit different. My favorite is the Nikkor 50mm. The Olympus lens is a good match though as its small and light.

Tempted to get the Leica adapter so I can try out my old 1938 leica lens on the Lumix...
