If this was the case for light how come that ISO 1600 on a GH2 in video mode will have exactly the same light gathering capability as a 5dmk2?

Because the 5dmk2 is line skipping (not using it's whole sensor) to get the video resolution down to HD spec.

Yes but it starts with more and scales down? please dont respond, I'm not interested in all this garbage, thank you.


Of course it starts with more resolution, but it skips horizonal lines becuase it's the easiest way to scale the image down for the video output. Read any video-centric forum (such as dvxuser.com) and see all the talk about "line skipping" and how it relates to why videographers are excited about the GH-2, becuase it has actual detail due to not line skipping.
