Yes, the internal mount adapter should work, but as I noted in the previous post, individual lenses, adapters, & cameras vary even when they conform to specifications, so you may experience front or back focusing, etc. Not a problem if you're using a mirrorless or other body w/live view, obviously, but something to keep in mind if you have to rely on an actual rangefinder.

Is that also compatible with the Amadeo adapter?
