Hello Anders,

As far as I know, the best MFT sensors are on the E-M5/E-PM2/E-PL5/E-P5/GH3. Exactly how the sensor performance of the GX7 and E-M1 compares is not really known yet, but based on what is known at this point, it seems unlikely to be significantly better.

Looking at the Image Quality page of the E-M1 preview where the GX7 image is shown along with the E-M1 and E-M5, the GX7 image looks less sharp than the others. Of course, that could be caused by the lens, but at this point I'm not convinced the GX7 sensor is all that good. I'll look forward to the full reviews.

In addition, the E-M5 image looks sharper than the E-M1. Could these be lens or focus issues?

Whatever it is, it's not a lens issue. With their new studio scene, DPR uses the Oly 45/1.8 for all MFT bodies (instead of the Oly FT 50/2 macro they have used in the past). The potential explanations that remain include differences with regard to exact focus point, AA filtering, and choice of f-stop. For some inexplicable reason, DPR used f/4.5 for the E-M5 versus f/5.6 for the other two bodies (according to their own technical info) and f/4.5 is probably slightly closer to peak performance, at least in the central portions of the frame.
