              this comparison is kind of weak, I'm sorry.
              Everyone is raving about the video capabilities of the Panasonic GH2 which has a more modern 3-core processors, also it has less moiré and a little less rolling shutter than all the Canons. Although Canon EOS do have more lenses, every lens can fit the micro-four-thirds mount of the GH2 with an adapter. The GH2 has a great crop mode that takes 1920x1080 pixels of the sensor (providing not only an extra tele end but also eliminates any moiré and banding as the image does not have to be digitally reduced to fit HD dimensions). The big question I had was about one of the features that Canon has for the T3i which sounded like this same approach to crop mode that the GH2 has... That would be interesting to read about...

              The Canon T3i has a built in mono microphone, whereas the Panasonic GH2 has a built in stereo microphone.

              I see no ratings on the sound quality of the recording. Do they record in mono or stereo? Which one has a better microphone?
