lenses which were adequate or better on film turned out to be inadequate on digital. they generally were not sharp enough for me to continue using, although in the case of the FA* 24/2, the chromatic aberration got way out of hand on digital. top quality lenses when used on film generally remained top quality on the *istD. many that were very good became acceptable or worse. some stayed acceptable. none ever got better. i got rid of any lenses that had too much difference between center and corner sharpness. also sold ones that showed too much falloff wide open too.

And also are you trying to say the sensor is revealing
the lens to not actually be as good as reviewed or are you
saying the sensor is inferior to film with regards to
the range of optical designs it can handle without sensor
induced artifacts?
