The GH2 does handle moire better -- but just barely. You will see moire from both cameras on the venetian blinds in the final shots -- the VG20 has it on both blinds, the GH2 has it on one.
The only thing that keeps me from buying the Sony right now is the price. The body-only price twice as high as a GH2 with a kit lens (and higher than the A77 or the NEX7). I think I'll wait until the price comes down (unless the GH3 turns out to be better ;-)).
I apologize for the focus and audio challenges, but I hope you find the comparison useful nevertheless
If you like the video, and it helps you decide to buy the VG20 and/or the GH2, please support this blog and future hands-on reviews by buying your camera(s), lenses and accessories through these links: Adorama, Amazon, Crutchfield, OneCall, and Unique Photo . Thanks!
