AF speed and accuracy
The V1's auto focus is very fast. I don't have the means to perform empirical tests. In good light, in my opinion, it is as fast if not faster than the GF2 and K5. It is definitely faster than the likes of the X100 and X10.
As for accuracy, it was not accurate all the time when using the multi-point AF setting. With the face detection on, it sometimes didn't lock onto the face. But it's definitely good enough for my every day use. Whenever the V1 wasn't 100% accurate, the results were still very good as the accuracy wasn't so bad that it rendered the photo unusable. Most of the time it was not 100% accurate was when I didn't prefocus with a half-press of the shutter button. IMO, the V1's AF system is more accurate than the GF2, K5, X100 and X10.
I was out shopping at the Outlet Mall on new year's eve. We didn't get there until 4:00 p.m or so, and it got dark quickly. The V1 performed pretty well for the most part. I used primarily the 30-110mm again, because it offers the fastest aperture at a somewhat telelephoto range 30mm (F3.8). The 10-30mm lens is F5.6 at 30mm.
The following photos were all taken in RAW and converted to JPG via LR3.6. They were all reduced to 1024 pixels. I cropped some, and applied NR to most of them. The V1's images even at ISO 100 show some noise. The good thing about the V1's noise is that they are a fine grain-like noise. They don't get blotchy.
I did not make any WB adjustments to these photos. And on most of them, I did not do any exposure adjustments either. As noted before, IMO, the V1's metering and auto WB is about as good as they get.

53mm, F4.1, ISO100, 1/640; got some nice bokeh there ... but primarily because the background was so far away from the subject.
