I am going to spend money I don't really have on a tele lens later this year for my crop body, so I really want to get the right one. If anyone has experience with these lenses, please give me some advice... here are my thoughts:
* 70-300L: fine but heavy lens, but is overpriced compared to the non-L version. Problem is it doesn't take a tele converter (thanks, canon marketing!) - but on the other hand, f/5.6+extender light capability would be too low anyway.
* 70-200/4L+2x: great and not too heavy lens, but using an extender doesn't make sense: In my experience, shooting moving objects at 300mm+ requires a large aperture at least of f/4 (next to a good servo af that is, unlike my 60d).
* 70-200/2.8L+2x: this is the combination I'd get at the moment - very short min. focus distance, great iq, still ok light capability w/ extender.
* the new 100-400/4-5.6L: I really don't know what to make of this: if the price prediction is right (which I doubt knowing canon rumors :-)) it is more expensive than the 70-200/2.8+2x combination, covers about the same focal distances and has worse light capability - why would anybody want to buy that? As I wrote above, extending a 5.6 lens doesn't make much sense to me...
And don't forget the SIGMA 120-300mm F2,8 APO EX DG OS HSM, this is a very very good lens !
