I guess if you think about the angles, a larger front element requires a longer and/or narrower hood - which a petal-shaped hood allows. But I do wonder whether that's really the reason, I find it doubtful actually.

I don't know about that....coz the 24-70mm has the same design hood as the 70-200mm F/4, just bigger in diameter~!

Probably because it if it was petal shaped it could actually be made longer. It's long enough, imo. I assume they decided it would more unwieldy if they made it longer. On the f2.8, if it was not petal shaped, it would be the length of the cutaway, much shorter and less effective.


Bohdan - I may be, and probably am, completely wrong.

Huh? Those two hoods are COMPLETELY different (in addition to the obvious size difference)

Why would you? The supplied hood is the one which works the best. Theres no need for a petal shaped hood on the F4.

Its a tool, not a fashion accessoire.

That's really unnecessary in my opinion, the f4 is on the league of its own and definitely not "inferior" to the f2.8 if that's what bothering you.
