Here're some screenshots from a short I did with my HV20 a while ago.
(It looks much darker on this Plasma screen, haha)
This thing performs amazingly in low-light if you put it into 24p CineMode (I think that's what it was called, anyway)
These scenes were done with practically ZERO light - we had some basic $50 work lights set up to give some ambient light, but no soft boxes or anything.
Sorry about the quality, this video is oooold and I could only find a 320p version.
Edit: The lighting here is anything from what I now consider "good", but it was a decent job considering how little we had to work with and it really fit well with the narrative.
