Not all data sheets are created equal!
Schneider's MTF graphs contain polychromatic diffraction MTF data  not just geometric MTF data. Schneider's MTF graphs are realistic indicators of actual lens performance in the field. If you are considering a lens from another supplier, it is in your best interests to ask exactly what their data sheets contain.
