I have already answer that, go back to page 2, BUT Canon, Leitz , Hasselblad Nikon etc has real MTF equipments and measuring of the lenses , not to be mixed by Photozone and others "MTF" tests .
There is no problem to measure a Canon lens at Hasselblad MTF lab in Gothenburg and compare that to others
I do not see an answer. Are you saying that the MTF curves published on Canon's (and Nikon's) websites represent real, empirically measured data?
we dont know if this is estimated MTF, Canon and Nikon has a predilection to exhibit estimated MTF results to impress
Which means estimating, calculating
And please, if you are going deliberately misunderstand me, keep going.
Ahhh...but we do
know. Canon's published MTF curves are calculated/theoretical, not
You have two possibly conflicting statements above - "Canon, Leitz , Hasselblad Nikon etc has real MTF equipments and measuring of the lenses," vs. "Canon and Nikon has a predilection to exhibit estimated MTF." Certainly it's possible that Canon has the instrumentation to empirically measure lens MTF (as Zeiss does, for example), and yet chooses to not show those data for their lenses. What is your evidence that Canon has such instrumentation?
