Hey people.
I'm still trying to figure out what lens to get, flipping between the Nikon 80-200 with a 2x (does the 2x keep the auto focus and metering?) and the 120-400 Sigma.
Both of these are getting beasty and i normal shoot freehand, although i think the weight will get to me after a weekend of shooting.
Any recomendations on decent but not bank killing mono's?

What are the things to look for, avoid, must haves, etc...
 
just a point but my experiences of a 70-200mm lens (a canon L so similar I think in quality to the 80-200mm you are looking at) are that a 2*Tc is not the easiest of TCs to use. My 1.4 is almost always on the 70-200mm and that works well, a focal length boost with little image degradation and only one stop of light lost.
Nikon make a 1.7TC and from what I have heard its a very good TC so that might be a better option if your after a longer lens.
If you are going to use a 2*TC to get the best results your subject has to really fill the frame as much as possible - if not its going to lack quality at the larger image sizes and prints.
I have some examples of my 70-200mm + 2*TC

*(note one can get improved performance with this combo if you use a pro end body - but they cost a lot!)*


Also if the 80-200mm is not an f2.8 (or wider) lens than auto focus is going to be tricky; whilst nikon cameras don't stop AF functinality due to small apertures on a lens (when wide open) after f5.6 the accuracy and speed starts to nosedive quickly (unless your using a pro end camera).
 
Good points, that was why i was sort of leaning towards the 120-400. I really need to be in the 400 range, i think the 1.7 might be close enough to work, and i have heard good things about it...
the 80-200 is a 2.8 so a 2x would still be putting me in the 5.6 range.

I'm off to Henry's tonight to look at these first hand and see what other options i have too...Maybe the 80-400 although i hear the focus is really slow on that.
