[quote=Maciel]Yeah, well...
It is the performance wide open where Leica lenses shine. So to say it is fine from f4 on is really missing the point. I would claim that one would be quite challenged to tell most 35 'crons from the 35 Color Skopar or Ultron from f4 up. If you don't believe me, look at MTFs.
It's a wonderful lens wide open or stopped down. Sharpness and MTF are not the only criteria for a lens. Eisenstaedt and Cartier-Bresson did not have any ASPH lenses.
