I had this lens standing unused in my cupboard. Since I have no Leica M and no intention of getting one I ordered a LM-z adapter DJ-Optical. Using it on the z6 is a mixed blessing, but fun at times. Wide open it has all kinds of optical flaws, but closed down to f/5,6 it behaves. It has very swirly bokeh with some find ok for portraits. It is quite easy to focus with the aids provided by the z6. Anyway, here is couple of examples for those who is interested. I might provide some more after more use of the lens. Both of these are wide open.
