I have the LX2 the preceded it and have *liked* this camera. The lens is great, the feature set was good (raw, 16:9 widescreen sensor) but it wasn't perfect - very slow with raw, noisy beyond ISO 100, did I mention slow?
This new version is interesting - faster lens, 40% better claimed sensitivity for better low light performance, hotshoe. I'm just hoping they gave it a bigger buffer to write those raw files - 8 seconds between images can be a drag.
Sometimes I just drag along the 5D and 24-105 L Lens - it weights more than my baseweight pack...
