A bit OT, I was passing a garage while driving today and the roof section
showed quite pronounced waveform distortion. Be careful when testing a lens
that the "reference" you are photographing is indeed straight and square.
How do you evaluate the negative/transparency when looking at distortion ?
I would suggest that most projector lenses exhibit more distortion than the
lenses used to produce the transparencies.
