Micro 4/3 vs a Full Frame Legend @ Admiring Light
M4/3 VS FF
For your own judgement. FF is still better..but hardly.
He is comparing GH2 and GX1. To me, these cameras are slightly behind the E-M5 performance. In any case, he seems to think that in the real world, the difference between GH2/GX1 and 1DsMark II is negligible because m4/3 has better resolution and detail, whereas FF has slightly better DR and noise control. I quote his conclusion here :
"Conclusion:
Well, that was interesting. You can make up your own mind here, but I see a few key points:
The GH2 and GX1 hold a real world resolution advantage over the 1Ds Mark II despite the similar megapixel count, likely due to a lighter anti-aliasing filter.
The 1Ds Mark II has better dynamic range than the Micro 4/3 cameras, which is visible as extra shadow detail.
The 1Ds II has about one stop better noise control in pure sensor performance.
Due to the resolution advantage, that one stop advantage can be negated up through ISO 3200 by proper RAW noise reduction, yielding similar noise performance and similar or better detail for the GH2 and GX1
In my eyes, color performance is essentially identical. There may be a difference, but I’ll be darned if I can see one with my eyes.
So, in my mind, for base ISO work, the GH2 and GX1 should be able to give you shots of similar quality to the legendary 1Ds Mark II, provided you don’t need the 1Ds II’s extra dynamic range. Even at high ISO, these tiny cameras are able to hang in there with the 1Ds II all the way through to ISO 3200, with the GX1 able to come extremely close even at ISO 6400. It’s an exciting time when little mirrorless cameras can achieve image quality at this level."
