If anyone is interested, I did a real quick, and not very accurate comparison of 5 cameras - GF1, LX3, LX5, NEX5 and DP2. It's just a quick shot of a color chart to see how they looked compared to each other. All I did was set the WB and tweak the EV a little on the raw files. FWIW, the NEX5 file was the only one that needed no tweaks at all.

All shot in IA mode.

Here are the pics.
