I've been pondering this. An ED lens (or one of Canon's "L" series lenses) should show less of this effect (chromatic abberation) than an average lens. This will depend on aperature used, CA is typically worst wide open, is minimal 2-3 f/stops down from max aperature, and tends to go back up a bit as diaphragm diffraction kicks in.
I'm wondering also if the effect is exaggerated in digital cameras, not only due to cheaper lenses, but to the fact that the image plane is the surface of a CCD, rather than layers of film. Since color film is composed of layers, it may compensate for this efect to some small degree. Also, if the lens of the digital camera is wide open (probably the case when shooting indoors w/flash), CA would be at its worst.
A good comparison would be using a film camera vs. digital camera, both wide open and stopped down. Ideally, using the same lens on a dSLR and regular film SLR would resolve the differences.

but on the flip side, digital slrs tend to have smaller sensors (than 35mm film) so that will help ca.
I guess a true comparison (for this purpose) is to use a full frame digital slrs.

Hmmm i remeber a little site on the net about ir cameras seeing through clothes. The sony video 8 was the one i think with night vision, all you had to do was set it in night vision and place a ir filter over the lens, bamo. Not very nice unless your the one using the cam😉
