Better Lens?

Was looking for a new lens for my camera today. Have seen some asum lenses for movie cameras and they cant be that special so they could not fit a normal Nikon, right?
There are lenses that goes from 10-410mm or with built "in" extenders 19-820mm.
That would be a sweet lens to have.

Anyway I did an experiment with the junk I have and the result is not all that bad. It not close to what "THEY" have but for a simple amature...

What "THEY" have:

What I came up with:
Nikon 70-200mm @ 200mm with extender 1.7 = 340mm
