So, how does the GH3 compare to the GH2 and other DSLR/DSLMs audio-wise? I'm planning to use the GH3 for solo run-and-gun shooting, so it would be interesting to know which improvements Panasonic has been able to make on that front. Has the signal-to-noise ratio improved? And what about the new shotgun mic DMW-MS2? It looks pretty solid compared to the crappy MS1, but is it really a substantial improvement? It'd better be good with that price tag... Has anyone had the opportunity to test it? I wonder if it is a serious alternative to the Rode Videomic Pro or the NTG2?
