The icons show 2 fluorite elements to be in this lens on the USA site, that seems to be an error (CaF2 usually is used in tele lenses).

In the japanese site they messed up the colours of the UD and S-UD elements (in the diagram both have the same colour, in the legend one is light blue but all elements for the rest are light blue).
Impressive lens.
** Someone at Canon.jp noticed the error, and got rid of the light blue dot with S-UD legend. Now both the UD and the S-UD element are still "UD" green. The image is hyperlinked.
