The rigid or DR Summicron aren't as sharp wide open as today's lenses, but they are sharp enough for most things,[..]
However, in case you are not satisfied with the f2.0 1 meter shots, you could take a look at photos done by these other amateur users of the same combo: Henri Cartier Bresson, Ralph Gibson, Gianni Berengo Gardin, etc...
Oh, I was very, very surprised by the 2.0-shoots. I wasn't expecting much and really was only looking for the typical leica characteristics in terms of contrasts and bokeh. I think I got it all with this lens (a shorter near-focus limit would have been sweet though).
However, I find it very hard to focus in dim light with lots of distracting lines in the viewfinder.
