Why do you have a different scale for almost all canon lenses that you test? Sometimes excelent starts at 2280, and sometimes it starts much lower. Are you using the same units everytime? Is it possible to use the same grading scale for all lenses? Also i noticed that sometimes your MTF values and those of dpreview.com dont match up, even for the same lens, is it because you test differently?
