This is a good solution, as if I understand the problem correctly
(haven't watched the render, don't have time right now, I should've
been in bed) is that the lens is too wide for the scale...
Think of using a real camera, and zooming out until you are at a 50mm
lens, you would require an object that covers a large area to cover
the lens entirely...
So, one solution would be to zoom in, another is to scale the scene up
(if you are using the realistic sky you'll have to do a scaling there
too, and you need to scale both numbers in the equivalent fields for
scale, as in 100 inches equals 1 mile or whatever it says, actually
means that the sky is only 100 inches high, and that this equals one
mile, I would use metric if I were you on this, as it's easier to
convert, fog doesn't seem to scale though, so you'll have to reduce it
if you scale up.)...
Both solutions should work, as the lens width doesn't change if you
scale the scene up, nor does the scale of the scene if you zoom in a
little...
