GH2 vs GH1 Piano Playing Basic

I am selling the GH2 and GH1 with a Panasonic shotgun mic. So I wanted to trial them side by side
GH1 on 45-150mm Panasonic lens at 800iso (had to decrease brightness in post)
GH2 on 19mm Sigma at 640 iso
Audio from Panasonic shotgun mic mark 1 with deverb and denoise added lightly

Well that was fun
