Canon 100-400 and 70-200

[Buszaj]

Bit of a silly question maybe, but popped into my head. Which lens will be longer when extended fully? I hear really good things about both of them. (The IS versions).

the 100 - 400 will be longer, the 70-200 doesn't extend externally it's a fixed length with internal zoom movement

The 100-400 (a push-pull design) is a bit over 12". More with the hood.
