I agree, and so do most but FF madness will always prevail and comparison with FF will always be pointless because you know what, FF is the only option, not! 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? using the analogy that both are downsampled to 2mpix full HD surely the sensitivity will be x stops better than a GH2, its not! the only thing that is different as well we all know is the observed dof and focal length, which is 1.8 x shallower and 1.8 longer on the equivalent f stop c/w with FF. IQ btw will be better on the GH2, sharper, less aliaing and moire, how so?
