I'll contribute the obligatory correction here:
No. It is still a 100 (or 400) mm lens. The focal length doesn't
change. The XL1 (or APS, or digicam...) just crop out an area in
the center of the image you get at 100mm (or 400mm). This may
sound picky, but if you use a 20mm lens on an XL1 and expect to get
the same thing as a 144mm on your EOS, you will be really surprised.
The angle of view is truly divided by 7.2 as you expect, but the
perspective is still that of a 20mm, wide angle distortion and all.
So don't try to get a good portrait shot with a 20mm on your XL1.
At least don't ever show that video to the subject :-)
