Really cool! Forgive my possibly ignorant question, but wouldn't a 2400mm yield a 10x shot?

The 100x zoom is the magnification at full telephoto focal length compared with the image at the lens's shortest (i.e. wide-angle) focal length. Those zoom figures might be a bit misleading. Quoted equivalent focal lengths (e.g. 24-1200 mm for the SX50's optical zoom) are those of a 35mm film camera, AKA a full-frame camera. Their lenses that give a similar view to human vision, called standard lenses, have a 50mm focal length. So a 2400mm lens would give a field of view in which objects appear to be 2400/50 = 48 times bigger (or nearer) than our eyes usually see them, i.e. zoomed in 48x. Cheers. Philip
