Does anyone have suggestions for a good camera lens optics book?
I was reading the Canon EF Lens Work III book chapter on "Optical terminology" looking for more information about "Principal points" and the optical axis for telephoto lenses. I have looked at some optics books at my local technical book store and I have looked on Amazon. I found this book. It was published in 2002. It probably does not have a chapter on DO (diffraction optics) lenses.
