Almost nobody has this lens, because (1) the Sigma 120-300/f2.8 is about the same price and weight, and (2) Sigma acknowledged a few years ago that the 120-300 was actually a better performer than their 300/2.8. Personally I think that Sigma quietly redesigned their 300/f2.8 recently (probably when it got the DG designation), because results from recent ones have been really good, but they don't acknowledge such a change.
I'm curious as to how the Sigma has faired in the real world as well since the Nikon 300s are impossible to get a hold of these days. If the IQ and AF performance is similar, the Sigma may hold me over until I can afford the VR or find a used older 300.
I have the 120-300 F2.8 that i got 1 year ago (or was it 2? cant remember)
I cant compare it to the nikkor cause i have never seen or tried it before.
But i gotta say i love mine
The downside is if you wanna use a TC, u can only use sigma's own TC.
Nikon 1.7 and 2.0 wont fit and if i remember correctly the 1,4 fits but doesnt work
(Kenko 1.4 TC doesnt work either)
Had been using it with my D70, then D200 and now D300, the AF is awesome (then again consider that before this 'upgrade' all i got is a AF 300 F4 and a 80-400 VR)
Used it for Motorsports (sort of), and used it a lot in birding
its very handheld-able, i used it to take a lot of pan shots of cars and birds
the downside i would say is the zoom ring is in a kinda wierd position. its pretty hard to pan and zoom at the same time. (or i just have terrible arm hand co-ordination. XD)
I am very happy with the lens, its sharp enough (could be better but good enough), personally i think the priceerformance ratio is just great
Here are some shots i got with it

Yep. It's f/2.8 at 120mm and f/2.8 at 300mm. It weighs about 8oz more than the 300/f2.8 prime lens, and it costs about the same $2700 on the street. It's got to be hard for Sigma to sell the prime when they're offering the zoom for the same price and better optical quality.
check out atleast the last 5 post I've done with this lens exclusively with a 2x convertor.
Very fast focusing and I've owned both Nikon VR lenses 300 2.8 and 200-400..
I don't know if I could ever let go of this lens because its so sharp, fast and has good range up to 600mm at 5.6.
