Nope - I'm saying that the current LensRentals MTFs are unreliable. Not because they're inaccurate, but because they done on a group of lens hand-selected by Sony and submitted for testing. Measurements performed on 10 randomly-selected copies may be somewhat different. Lensrentals themselves have said that they will re-test it with randomly-selected copies once the lens is released.

More accurately Roger Cicala said "...10 new-from-box copies tested and averaged. They are Sony’s own copies, however, not the usual lenses we’ve bought off the shelf. I’ll repeat the test in 6 weeks when we get our own copies, but I have no reason to think it will be different. "
