[Leica] Adapting Leica M lenses to Leica R (?)

[red735i at earthlink.net (Frank Filippone)]

No.  The 90 head and the 135 heads are better bets.... and I am not sure
even then that it would work at 10 feet.......

Does anyone have a Pickett or K+E slide rule that can calculate the focus
range a 90mm lens head on a R body ?

Or better yet, someone will probably be able to look it up in some Leica Lit
of the 70's or 80's period.....

Anyone had experience with or know of lens adapters that will put a Leica M
lens on an R camera mount? I know that such a combination puts the M lens
too far from the body to focus on infinity - sort of like adding an
extension tube to the M lens. But would a 35 or 50mm M lens focus close
enough - say down to ten feet - to be of use for some situations?
