Panasonic GH2 with 14-140mm. Both warmly recommended. High-quality, speedy, compact all-round kit. The GH2 is not cheap, but I think the new G3 will do as well. And the lens is the only really sharp 10x zoom lens I have ever tried, it's exceptional.
By the way, notice on the left side of the picture of the road and the shadow, there's a smudge, which looks like a smudge on the lens. Well, it is! I think that's the first time ever I have seen something on the lens being visible on a picture, but then this is the wide-angle setting and a very small aperture, so even a tiny smudge (half a pinky nail size) becomes visible. The other pictures are mostly on longer focal lengths and darker subjects ( meaning wider apertures), so it's not visible due to shallower depth of field.
