A G10, which I have, is also no longer relevant, other than at low ISO settings. The G11, which I'm not planning to get, seems to beat most of its peers at the higher ISO settings. From the tests I've seen, I'm waiting for the G12. The Panasonic line is still far noisier than I'm comfortable with. S.d.
