Small preview of my weekend test. C3 was using a Sigma 19mm, E-M5 was using the Panny 14-45. Shot it under exposed. Boosted exposure +2.0 and shadows +100 in LR4. The comparison with the NEX-7 should be a lot more fun but resizing and doing all that is a bit of a pain. RAW on both of course. However, I'm very surprised how well the E-M5 did here in this made up torture test. In the past, this sort of torture test would have had MFT fall on it's face. The C3 retains a bit more shadow detail but the E-M5 isn't terrible here either. In the normally exposed file, the E-M5 seems to have a weaker AA filter and has overall a bit more detail than the C3. I'm not 100% sure if that has to with funkiness from the difference in aspect ratio however. Will be doing a lot more tests.
