And here's a demonstration of this idea:

This is made by stitching together around 600 photos taken with a Nikon D1X and
one of Nikon's Nikkor AF VR 80-400mm f4.5-5.6 lenses.  And that's *only* a 400mm
lens... put something like a Nikkor 1000mm lens on and...

I guess the moral of this story is, in the real world when you zoom in, there's
more detail (and something that might not appear to have much detail from far
away has more detail the closer you get).  With a virtual 3D construct when you
zoom in, there's less detail (and something that might appear to have a lot of
detail from far away has less detail the closer you get).

Real world for win!
