This is not a test.. it's a waste of time

Sorry to be blunt but you can't make a test and expect results that you can base any analysis on if everything in the shots is different.

Different focal points, for a starter. but most of this test is not test-worthy because the systems themselves do compensations.

Re-do your tests with 100% manual, same iso, same shutterspeeds, same focal point (take several shots choost most accurate focus for each)

Also make sure you are not engaging noise reduction, lens-correction parameters, etc (shoot raw, develop with all settings off.)

Lens-corrections do more than you might think with an image. when talking mft, people tend to forget that a 25mm lens is actually a wideangle lens - pretty wide wideangle too, which comes with some severe perspective isues. regardless of the fov multiplier, you can never get away from the fact that a lens of a certain physical mm is a constant.

Now that you have shot everything ultra clean , without software or in-camera compensations, etc etc etc.. now compare.
