It's actually not "sort of true", its a law of physics, and therefore true for the world we live in, as it is built according to the same set of physical laws this is part of.. Focal length actually has nothing to do with this, see my reply to Yakim.
Kind regards, Wim

You are reading very defensively. I said it is soft of true that light fall off is exactly the same with all lenses, and I am correct in that, I even pointed out that there can be many factors at play (including the focal length changing differently with different lenses, which does influence exposure too... if the focal length changes but the aperture stays the same).
