One of the things many of those who are dismissing the LX3 seem to
ignore is the faster lens. At WA, the LX3's f/2.0 lens is allows
twice as much light in as most other's (including the G9 and F31)
f/2.8 lens. And at full tele (yes, it's only 60mm) the LX3 is still
only f/2.8. So at WA (and it's 24mm on the LX3!) what you're seeing
at ISO 400 on the LX3 is equivalent to the G9's and F31's ISO 800. At
full tele, it's even less of a contest. Comparing apples to apples,
I'd say the LX3 is quite impressive in low light.
