Leica R lenses

When you have a M camera you probably have a bunch of M lenses.

So all the equivalent focales lenght (wide to 135mm) won't be really interesting.

Only the few who have long télé might use this possibility but the M would be clumsy with those big lenses.

Now you may have "R only" owners who, in despair of not having a R10, may go for this combo M body+R lenses, it's a bit odd.
