I think I will wait till I see the RAW before I pass judgment, but I see some noise in the shadows.
I had beeing waiting for the LX7 having had the LX2 and currently using the LX5, but I can't see enough in the LX7 to make me replace my LX5. There does seem a trend toward increasing the video capabilities of cameras. I assume this is one of the reasons for the chip change but I have never shot a video on my camera and probably never will. I had been hoping for a larger sensor but never mind my LX5 will have to do.
