I'm late to this thread, but thanks a bunch for doing this. Really excellent test.

Next, I took a look at the shadows. There wasn't a lot of extreme shadowing in the frame, but the bridge above, of course was the place to look. This much shadow recovery is equivalent to a 3 stop push. There is a lot of noise for both cameras in the pushed shadows, that's for sure, but the E-M5 again retains more detail, has better noise control, and retains the rust color of the bridge steel. The GH2 loses the color information and a lot of the darkest detail.

That looks like a fair assessment to me. My question is this - how far can you underexpose shadows without losing fine detail on the E-M5? On my D700 for example, I can get away with around 1.5 stops of underexposure and still have some semblance of fine details after processing, whereas on the E-PM1, even 0.5 stops causes significant degradation. Thanks,
DH
