I have a few images from the a7 taken at ISO1600 but these were not taken under controlled conditions, and were JPEG, not RAW. Furthermore, the NF (noise filter) on the a7 was on the LOW setting, whereas the E-M1 was being shot in RAW with all noise reduction turned off. I may do more tests along these lines if I can find the time (and remember to) but off hand, it would seem to me that the noise is more controlled in the a7 at ISO1600 compared to the E-M1. This is particularly so with colour noise. That, and the higher resolution of the a7, which allows for down-sampling, means that it produces cleaner images when used at ISO1600 (what I have images of.)
