Autofocus may be a no-no, but there are times when some kind of focus confirmation would be nice. There are occasions when I've been shooting in very low light with my M6 and Nocti when I've found it very difficult to focus, especially if the subject isn't high contrast, or has a highlight in the focus plane. Of course this also precisely the same situation where an AF system would struggle. Perhaps Leica could use some of their laser rangefinder experience to develop a new system :-)

As Andy says not all Leicas are rangefinders. I've been using R lenses on a Canon digital body for some time. There have been occasions where auto-focus would have been useful, but manual focus has been more effective than I was anticiating.
