Won't work. As you zoom, the visual apearance of the
aperture changes because of the change in lens
magnification, even if the actual diameter doesn't
change at all. You can't determine this visually.
You'd need to disasemble the lens and actually measure
it to be sure.
On top of that, since the aperture blades in EOS
lenses are controlled electrically, the compensation
might not occur at all with the lens removed from the body.
