For the record, I understand his previous posts crystal clear. I think it was a useful and valid contribution that many of us, including myself, were wholly unaware of.

Theoretical data does not always indicate a better lens than practical data.

Maybe not, but comparing these two mtf charts don't show this. What if the fuji model is set to a different distance from lens to target than the lens rental rig? In fact I'll just about guarantee that it is and that one factor alone has a huge influence on MTF charts.

Or they could be using a different wavelength of light for testing, or different pixel pitch. Any slight deviation makes comparison impossible.
