I have watched a lot of videos on this topic. The problem is that you walk away from them scratching your head.
Mark Wallace over at Adorama does an excellent job of explaining in a very simple way exactly how this works. Granted he does oversimplify the subject. Which he admits during the video. However, I don’t think you really need to know the more technical aspects unless you’re planning on building a camera lens.
I think you’ll walk away from this with a better understanding of exactly how focus works and, why one lens costs so much more than another.
