Talking about these Four Thirds lenses brings me back to another great Lens by the Panasonic-Leica partnership, the Vario-Elmar 14-150 f3.5-5.6. I think this lens coupled with the Panasonic L1 is one of the best camera/lens combinations I have ever used. Looking back through the images I have made with this combination makes me ask myself why I rarely use this combination these days. Well, if I had the time I would, but I'm a bit of a camera geek. I like using different cameras and lenses. The lens isn't all that fast and can only be used in good light. The high ISO performance of the L1 is also restricting. I don't think I've ever used the L1 over ISO 400. Todays cameras are much better in this respect and offers more situations where these cameras can be used.
