I used tripod to take this shot. I also found that this combo(300mm 2.8+2.0TC) can't effectively track fast moving birds(e.g. turns) because the 2XTC makes the speed of AF a lot slower. who care about weather seal if you can't even make the bird in focus? or constantly making low grade pictures?I want to say it again, 70-200mmII is very nice but it just not ideal for bird/wildlife, cause it's just too short and slower AF, at least I don't want to spent more then $2500 on a lens and TC that only make" pretty good "quality pictures[]

I will agree with you too if this is another priority for bird/wild life, , but I don't think it is. shooting in field usually has lots of lights and you can always use flash or tripod to help. 400mm 5.6 has no IS, but it's a well-known lens for BIF. Nate has a lot of great bird pictures(not just BIF, and he always hand helding) took with this lens, I would hardly believe that the IQ from 70-2002.8II or with 2.0TC combo will be better than the IQ from 400mm 5.6 in a constant basis if we talking about bird/wildlife.
if weather seal and IS are not the priority, then what's the whole purpose of choosing version II over version I? the IQ right? isn't that the version I +400mm5.6 a lot better than version II+ TCII in the whole range of 70-400 if we talking about bird/wildlife for a given price range?
then again, I'm still very new in this photography thing, I don't mean to argue with you , please correct me if I'm wrong, Daniel , I'm willing to learn, thanks.
Damn, It's so late now, I'll be very sleepy tomorrow at work![:@]
