Oh, yeah - I got confused a bit with those product names :) The only thing I don't like about my Lumix is the performance in low light situations - ISO 2000 and above introduce so much noise that the pictures are hardly usable. The Sony should be much better in that regard. Cheers!
Yes, it can see in the dark compared to my previous camera (Canon EOS Kiss x5). I think that maxed out at a very noisy 6400 ISO.
