Further, the film companies have differing emulsion build up designs,
including Fuji "4th layer" in some negative films. I never heard of
needing special lenses for that...
Or special lenses for black and white...
That was the first thing I considered. I even asked the poster about that
and several folks have replied that he's full of $#@!, but he has apparently
disappeared.
