get a 70-300 imho it'll be a damn sight lighter than an 80-200
at that length you won't really need 2.8 imho and if you're on safari i can't imagine there being a shortage of light
Sorry but your wrong. There will be plenty of occasions where f2.8 will be required.
I own an 80-200 f/2.8 AFDn (selling it though, but it needs work) and 90 to 95% of my work is done using this lens. From listening to countless safari trip stories from a friend he has had more success with the 80-200 range over anything else. Bear in mind that you will be limited on space and weight too.
The 80-200 and 1.4x will be the best combo.
looking at hiring this lens for my safari in april, i will be pairing it with my nikon d50, and using a nikon 300 f4 with 1.4x on my d90.
is this a good combination to take or should i look at something like the sigma 120-300 2.8?
This is a bit harsh, eh? Alex says there won't be a shortage of light (which I agree with), you say he's wrong but offer no evidence. You say you use it most of the time but it's your friend that actually goes on safari. You talk about the range being useful, which is covered (and more) by the 70-300. Then you say you'll be limited with size and weight, which Alex already said, which means the 70-300 is even more useful! Bad day?
Its irrelevant whether or not I was there. The information and statistics come from a reliable source. There are many occasions where f/2.8 coupled with high ISO's have been used to achieve the photograph. I would prefer to sacrifice 100mm in focal length in order to attain a photograph at f/2.8 over pushing the ISO up a stop or even two.

Will the 80-200 AFD take a TC?
Yes.
Yes.
But only a third party one, like a Kenko

Sam. Keep a wide angle on the D50 for landscape,sunset,sunrise stuff.
Sigma 120-300 on the D90 will give you that range at 2.8,put a 1.4TC on it and you will get up to 420 at F4.
That is my recommendation.
also how well does the nikon 70-200 take the 1.7x?
ok thanks fot that, is the IQ lose reallt noticable with either converter?
