Here's a trial version, with a totally arbitrary relationship. The Ball Z is taken as the focal length, and Ball Y * 2 is taken as the f-stop. See if this gives you a more empirical sense of how the relationship should really work..... Edit: in case it's not obvious, you move the ball, make sure the ball is still selected, then hit the script.
