I know it is way off topic, but if you can see a big difference in detail, it isn’t due to the camera. It may be you not getting the best out of your gear. There are numerous examples about how much detail a camera like the EM1 can extract.Any chance in the Mu-43 section of keeping a few of the main image sections for wild life and landscape.
for images of birds, lizards and landscape Mu-43 may not look too good if mixed up with a lot of FF. In the camera club I am in you can really tell the difference in the details. This could lead to less Mu-43 photos being posted.. possibly
