For those of you who don't hang out in the General Photography Talk section, you might be interested in my project, putting together my trusty ol' 30D with my 100-400mm lens and a Kenko 2x TC, and then adding a Better Beamer flash extender to light up the resulting 800mm (optical/magnified) focal length!
Here's the thread that got me moving:
