The EM1 again holds its own in this comparison, with if anything slightly lower measured noise than the E-M5. It's a very close match to the 24MP Nikon D7100 in this pixel-level analysis, but this means that the higher pixel count camera will give visually-cleaner results when images are displayed or printed at the same size. Overall though, it's again a good performance, with the Micro Four Thirds camera looking pretty competitive with its APS-C sensor counterparts.
