Panasonic is releasing a LX2 camera soon, which they claim has much lower noise. On the other hand, the new Venus III image processor they are using is said to smear a lot of detail, at least in another Pany camera that is using it. I will take noisy detail over smeared clean shots every time, but it's not clear yet how the LX2 will fare in that regard. While the LX-1 has a lot going for it, I sold it and got a Canon S3 instead, for the better zoom range and great video. The lens in the LX-1 is sharper but much noisier than the Canon.
