I am buying a D7000, and at the same time I am buying a Sigma 70-200mm 2.8 DG Macro HSM II. I also want to buy a 2X teleconverter:but don't know whether to buy a Nikon TC-20E-II or a Sigma EX APO 2X.
OF the two teleconverters, I don't know which one will work, if any!
Anyone have experience with these combinations?
Thank you, Nikonians!

As a general rule, use the same brand TC as the lens although there are exceptions.
The Sigma TC should perform better on a Sigma lens that the Nikkor TC. The Nikkor TC will perform better on Nikkor lenses than the Sigma.
The new Nikkor TC-20E III has proven to out perform the TC-20E II by a significant margin.
Good Luck and Enjoy your Nikons!

Nikon's TCs will not even allow the Sigma lens to mount: there is a tab on them that precludes unsupported lenses to be mounted. An adventurous few have ground off the tab, and have found AF to be less than reliable when other lenses are then mounted. Needless to say this voids the warranty!
I have found the Sigma 2x TC to be decent but not great. I used it only as a last resort. In fact, it got so little use that I just sold it. Despite my comments about IQ, it is far better than generic 2x TCs. Note also that my experience with the Sigma 2x TC is that it results in somewhat jittery focus even with f/2.8 Sigmas. This is similar to what I find with Nikon's TC-20EII and III and f/2.8 Nikkors. It's workable but you won't ever wonder whether it is mounted... Still, if you're determined to go with a TC for the Sigma 70-200, the Sigma TC is the one to use.
As an aside, my Sigma 2x TC has always caused my Nikon AFS lenses to go nuts - AF is not just unreliable, it is actually reliably unusable. I've only tried this with the 80-200/f2.8 AFS, 70-200/f2.8 AFS VR-I and 400/f2.8 AFS-II. Other folks have reported better results, but mine was very consistent.
