hmm, i have read that some people like the ball heads on the mono's some don't also.
i'd love the 70-200 but my next purchase will be the tokina 116 wide angle for work purposes.
next on the list after that is the 100-400 IS L or maybe the 70-200 with the converter. not sure if the converter will work on the 40d so something to look into. probably just go straight to the 100-400 and put a converter on that if it fits and try and get an more reach.
there was a chat on seabreeze a while back about the 70-200 with converter versus the 100-400. both excellent options.
For reasons I don't understand, if you use an extender on a lens with an aperture greater than 2.8, you lose auto-focus. It is not dependent on the body, just the lens.
You also double your aperture value, so if you put an extender on teh 100-400 f4.4-5.6, you lose AF. If you put it on the 70-200 f2.8, you retain AF, but 2.8 becomes 5.6, which the 100-400 is at 400 anyway.
Beyond that, the 70-200 is probably a superior lens for general use. It is certainly a lot more easily carried around and easy to use on a daily basis.
They seem like a big lump when you first get one, but after a while, they are become unremarkable. Ther 100-400 always has that slide out thing if you let it dangle around your neck. Great lens though. I've got some great dolphin shots I took from CApe Byron looking down with one.
The deciding factor though, is that with teh 70-200 you can take teh extender off have get f2.8, which you can never do with teh 100-400.
So what, you say ?? Trust me, you don't know what you are missing until you have it.
It's like comparing a good free-ride board with a sppeb board on the speed bank. ONe is good, the otehr is better.
You can borrow the ball head to try out if you want.
