I think part of the problem is with the lenses. Digital image capture 
shows up every flaw
and limitation in a lens. Obviously if you are only using the center of 
a lens that was
designed to cover a receptor bigger than the capture device it is 
sitting in front of you are going
to get good results.  It would be very interesting to see a comparison 
of some Leica glass vs. the
equivalent Nikon/Canon lenses. I wonder if some of the problems we are 
seeing is due to the glass.
