I'm using a Kenko 1.4TC with my Sigma 150-500 and it still maintains Autofocus. I'm not sure if Nikon TC's work with this lens, if they do wyou will probably be reduced to manual focus. Sigma's website state you can use Sigma TC's with it, but again hit & miss whether AF will work or not. I do find the Kenko TC will perform well as long as enough light is getting to the camera, AF slows in low light, but I find MF i actually quite easy on the 150-500.

Nikon t/c's are not mountable on Sigma HSM & AF lenses.
I think there is a lug on the t/c that prevents them coupling up.

DG Kenko Teleplus 1.5 x converter in Nikon AF mount
Not sure if it will work on your lens but i had this bought for me and have never used it. i think it cost about £90 from Castle Cameras in Salisbury.
Kenko Digitally optimised converter increases the focal length of the lens it is fitted to by 1.5 times e.g. if fitted to a 200mm lens the effective focal length becomes 300mm. With the increased focal length comes a loss in lens speed of 1.2 stops.
Kenko recommend that the converter is used with lenses with a maximum aperture faster than f4 to retain auto-focus. With slower lenses it will be necessary to use manual focus (although top end Nikon and Canon pro bodies will usualy retain AF down to an effective aperture of f8).
This converter is 6 months old and is in mint condition with an asking price of £70
