I can't argue with you as I have a dslr myself, only aps-c but there are things I can do with it that I can't do with compacts and one of them is I can't part with my macro glass. Canon has the new consumer FF camera, not as big of a profile but that big sensor.. that and a wide angle lens.. I have the 28mm 1.8 because it's wide, can shoot close and allows for shallow dof with great blur. It's not as wide on my camera but would be on FF. 85 1.2 is a beauty too though out of my $ range.I use the 14/2.5, 20/1.7 and the 25/1.4, but there is nothing wrong with the camera or lenses it's just the my desired result that is some what unattainable. I wouldn't be selling my M43 camera, but rather adding a new camera.
I did this during the recent photo challenge. The results had a very three dimensional look.. it was fun but had I more time, because it was starting to rain, I would have worked my background better and eked more out of it.
