This 5D/135L combo does not cost an arm and a leg but I think it will match the sharpness and resolution of a Zeiss or Leica lens or even the esoteric 200/1.8 on a 1Ds2. I think my 50/2.5 macro lens would perform just as well on a 5D. Shot at ISO 200 at f2.8 and 1/320 sec. Pretty impressive don't you think?
