The closer the rear element is to the film, the winder the spread on the film. Thicker emulsion films will be more pronounced than thinner emulsion films. R lenses do not have this problem because they are retrofocus designs. The rear element is still way out in front of the mirror. A long ways away in terms of light ray angles. Jim
