Actually, it won't even come close.and for the cost of a 2x TC a 70-200mm f/2.8 IS will easily match the sharpness on a 100-400.
Same here, but I have had 2X 100-400's and they were both sharpActually, it won't even come close.
(Had both lenses, the 100-400 was sharper at F5.6 than the 70-200 + 2x Canon TC.
And AF was quicker.
don't think that anyone will disagree that a 300/2.8 perhaps with a 1.4x TC is preferrable in terms of IQ but it's also considerably dearer (& less flexible).As I had a TC an a 70-200 and the intention for a 300 f/2.8 I gave it back.
My 100-400 is plenty sharp enough, as are most other peoples i have come across.

You had to point that one out didn't you...Staying out of this thread must have been a real test of your self restraint...(for which we're all more than grateful)

Its not very fast and its not very sharp.
by that I mean comparatively. F4.5 is not fast by modern zoom standards, nor is 5.6 at 400mm, and for the cost of a 2x TC a 70-200mm f/2.8 IS will easily match the sharpness on a 100-400. The point Im trying to make is the fact that most sport 'togs (myself included) wont bother with one as we'd prefer to carry a TC with our 70-200's than another Kilo of lens. Im into motorsport and personally Id have a 300mm f/2.8 and have the weight than carry a lens that offers me such a limited functionality.
Personal preferance. Didnt mean to offend.
I'm no fan of the 100-400 but it's not that bad. I would class the 70-200 IS with a 2x as emergency use only.

Yes canon could do with replacing this lens and a 2.8, non push/pull version would be brilliant but really you just have to use it within it's limits.
It's very strange how quickly you get used to push pull again

by the way is that CT who was at marquis Drive and gave me a go on his 500f4 cause he was a real help to me when I asked his advice on the 300f2.8
Yo short arse!
