Hey, that's great! The
Using M Lenses on Fujifilm X Cameras article definitely made some rounds. Welcome.
Without have the lens handy to check, it's hard to say. Though I suspect its longer focal length and slower speed - should allow it to work with the Fuji M Adapter. My Tele-Elmar-M 135mm f/4 works great.
The problem lenses are the ones that are wider and/or faster - as the back end of the lens either sticks out farther or is wider... And this interferes with the electronic contacts in the Fuji adapter.
If you (or someone else) could provide measurements, I could check it for you.
