Looks good on paper but never get version one of anything. As dpreview stated---noise, noise,noise.
It underperforms badly at ISO ratings of over 80. You can see this on the reviews test photos.
Everything else about this camera recommends itself to the serious backcountry user--the manual capabilities, the format options, shooting in RAW (very nice) and a reasonable weight (under 9 oz.).
Leica will have a version of this camera out for next year in a slightly different form.
Perhaps, when Panosonic uses a decent sensor on this camera I'll snag it. But until then, I can only hope that Canon and the rest will be moved to produce as potentially a versatile camera as this.
The name (Lumix) has to go, too. Makes me think of lummox---as in "stupid, clumsy". ;-)
