Nikon's MTF are measured. Canon's MTF are calculated. Thus, they can not be compared.

Nikon's MFT are calculated too... but the person was talking about the MFT results from the photozone reviews.
Nikon has a replacement, the 50-500 SIGma, the 150-500 Sigma and the 120-400 Sigma <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='
