Just for fun, I did a search and found the follwing link: http://www.phootos.com/Library/resolvetest.htm
This fellow claims that a Hasselblad CF 80mm / 2.8 T* at f2.8 is hitting 500 lpmm, and a Contax G 45mm / 2 is getting 530 lpmm using his testing procedures. This would seem to obviate some claims that small format lenses are significantly better than 35mm lenses, and agrees with what I have personally obseved about the Carl Zeiss lens for the Hasselblad.
