This comparison is about lens not sensors. If you look at the Oly corner, it's much sharper than the Sony Zeiss.

It's amazing how a smaller image can trick us into thinking it's sharper.  
I tried it both ways:  1. upsize the EM1 image so the scale was the same as the NEX-7 image.  2) downsize the NEX image to the same as the EM1 image.  In both comparisons, there's no question the NEX-7 image is more detailed and you can get significantly better sharpness out of it.  This applies across the frame.

I have to say the Oly image is a bit ratty-looking for a base iso image.  The NEX7 image is smooth and still looks smooth after sharpening it similarly to the Oly.  Perhaps it's being crippled by poor processing?
