p.3 #1 · Are you a Leica M camera or Leica lens person?
If one is interested in a film RF experience, there's a huge world of options outside of Leica-branded stuff. Some have compatibility with M mount, many more with LTM, and then there's Contax mount (with some Nikon S compatibilty). Beyond that, there are fixed-lens RF cameras (popular in the 1970s). One of my favorites in this category is the latter-era Contax T with optical RF and fixed 38/2.8 Sonnar. And, yes, I do own Leica film gear for the, ah, cachet.
