Our computer uses zernike 1,2,3,4 for to correct the all aberrations on the film plane . Same computer uses zernike 4,5,7,8 for to correct the all aberrations on the film plane for another generation. At the end , there is no aberration on the film plane for these lenses. Do the signatures be different ? If yes , there is no meaning of MTF test. Umut
