If this has been asked already on this forum I apologize, it was difficult to search for with every topic about lenses coming up. I am wondering what exactly the millimeters of each specific lense refers to. What are the measuring that makes a 16mm lense different from a 32mm lense? I've heard it is the distance from the middle of the rear element to the film plane, but the source wasn't sure. Any links or answers would be much appreciated. Thanks.
