This does look good - maybe Leica made it a bit more tele centric to make their life easier!
As for other lenses . . . . don't forget the Zeiss Contax lenses - they can be had quite reasonably, and they're right up there in the Leica territory.
35-70 f4 - lovely lens (and lovely shot as well Ario)
Lou - thanks for the kind words - I might change my mind when the 24-70 zoom comes out - who knows!
