I use M240 with VF-2 Olympus with a bunch of SLR lenses (Leica R, manual Nikkor, Canon FD, Zeiss for Contax, etc. ).
Results are top.
Just some "time parallax" (same as liveview anyway) when in use with moving subjects.
But for static "macro" use, nothing to complain, great pictures, as good as the lenses can deliver.
