Thanks for the articles though it would be nice to have a more direct answer to the question.  I got the impression from your comments that the pupil magnification had some important implication on the output from these lenses.

I’m not an optics expert by any means but the little that I had read on that issue seemed to suggest that pupil magnification doesn’t typically have a significant impact on the optical properties of camera lenses.  For this reason, your seeming to suggest otherwise peeked my interest.

If there is something important to the image making process that I can learn from a better understanding of this then I definitely want to know more.  If the main benefit is to just understand optics better for the sake of knowledge then I probably have more pressing things to use my time on though a better understanding of optics would be a nice luxury.

So was there something specific you had in mind when you made your comment?
