Maybe but there is possibly an angle of incidence factor ie film is not as sensitive to the angle of the light hitting its surface whereas the CCD cells really function optimally when hit by perpendicular rays. I suspect that symmetrical wide angle RF lenses like the CZ Hologon whose rear element is almost touching the film may cause problems with CCD imagers?
