I was interested in MTF 10 too.
I have found the ISO12233 crops at digital-picture.com very usefull. They talk the full story about contrast and resolution.
E.g. look at http://www.the-digital-picture.com/Revie...&APIComp=0\

It is clear to see the contrast advantage of Tamron 70-300 VC against Canon 70-300 IS.
However they both have similar resolution.
