Re: Bizzare decision, if that is true.

The A77 has a SLT mirror gobling up light. Compared to the D7000, K5 and soon, the K5N, the GH2 is indeed over a stop worse at base ISO:

The average difference of SNR, DR, color depth, and color sensitivity is almost 1.5 stops at base ISO. At equal ISOs the difference is about 2/3s of a stop. Thanks to the exceptionally low read noise of the Sony 16mp sensor it really pulls ahead when you drop the ISO.

No, m43 is not lagging more than size would indicate. It is about 2/3 to 1 stop. That is about the difference in general throughout the range. If you look at the alpha77 you'll notice that at the lowest ISO, it indeed is better but further on it is about 1/2 stop or so. According to DxO. According to other tests, the gap may be smaller.

I am really happy with the Gh2 at base ISO aswell as ISO 3200. I know Pentax K5 and D7000 will do better, but to me at least, not enough to get me behemoth lenses and large bodies. That is too big of a downside.
