I've seen different terminology on this site. I was always learned that a lens's aperture diameter was found by dividing the lens' focal length by its aperture diameter. Now I am seeing divide the focal length by the entrance pupil, not the aperture diameter. Now are there two different parts to a lens by these names or are we tomato/toamto - ing this one?
