I get what you mean by focal length. The image is still exactly as "far away" from me no matter which camera body I'm using. The difference is how much of a -- for lack of a better term -- "wide angle" you're seeing. How much of the picture you're going to see when you look through the lens. There should be a technical term for that which is understood by all. Again, I don't know how.
