However, I keep thinking they could have made it more compact. As it is, I still find it fairly large (although much lighter than its 2.8 counterpart).

How do you figure this?



The dimensions on the old 70-210 f4 are:

Approx. 76.5 mm dia. x 156 mm extension from flange

Weight: Approx. 760g

13 elements in 9 groups



New 70-200 f4

Approx. 78 mm dia. x 178.5 mm extension from flange

Weight: Approx. 850g

20 elements in 14 groups.



So with VR III and 7 more elements (and 5 more groups) it's only 90g more and 22mm longer.



Of course if you are a lens designer (for Canon or Zeiss) then I apologize in advance.
