That is big. A bit out of my range for sure.

Why does it need FCC and FDA approval before it can be sold in the United States?

FCC - Most electronics generate EMI (elecronic magnetic interference) because of their high-speed switching circuit inside, like clocks from processor for example so the product is tested not so much for the EMI susceptibility it get from other devices, but what it might do to other product such as a PaceMaker for the heart come to mind...

FDA - Doesn't most glass contain lead (which seems to be making the news lately)? But then again this has to do more with radiation according to Canon's own footnotes (21.C.F.R.ยง 1002.10): http://www.fda.gov/cdrh/radhlth/pdf/accrpt01.pdf

I'm sure this is a fantastic lenses, but for its cost you can actually get a 600mm f4 L and possibly a Sigma 800mm f/5.6 EX which is already on the market for a while... BTW this Sigma 800mmm f/5.6 already weights less than the 600mm f/4!

-> IMO Sigma got it right in their 300-800 f/5.6 zoom (i.e. you'll get both focal lenghts) - Perfect combination of cost/weight and feature to the hobbyists who already used this type of lens on a tripod...
