Nathan,

>>MTF is equal to how much of the line pairs is reproduced by the lens<<

a lens cannot produce an imager that has higher contrast than the original
scene, so the MTF value has to < 100% for any spatial frequency. A film
can, and I believe the original question dealt with MTF curves for film.
