And I used my Noctilux extensively and blew the shots up to 16x20 and the focusing was always spot on. Sure rangefinder focusing can go out but in the long run its many times more accurate than a groundglass up to a lens I think 120mm's. That's a math thing Brad the Leica rep told me. Leicas use has long been much about the superiority of its rangefinder a mechanical marvel that was softly tweaked through time but was good at the onset. One hates to see it written off as inferior by the first high tech metal munching marvel technology which comes along with predator graphics.. I don't think it has..
