I am led to believe a converter is a no-go with this lens.
I used to use this lens on a Nikon D70 with a kenko 1.4x pro 300 DG teleconverter. Results were acceptable in good light, & it even retained AF(although it was fairly slow). It did hunt around in poor light. I also had to have it supported either on a tripod or beanbag. The Sigma will not retain AF with this lens.

I now own Rob's converter, and it works with the lens, but the quality suffers. I tend to only use the converter with "smaller" lenses when i need to travel light and can't take the big Tamron lens.
It's an OK gadget to have, but don't count on it being able to "get you closer" - it the bird only produces a "blob" because it's too far away, with the converter all you get is a slightly bigger blob with the converter!
But, it does still autofocus - if somewhat slower.
Not sure, but i suspect the Tamron and the Kenco might actually be the same?

I own a Big T - and never used a TC .
Even Tamron company does not recommend using a Tc with the 200-500.
( I asked Tamron comp, and even B&H - do not recommend one ).
The lens is great - as it is , and no need for attachments .
If the bird is too small - you are not close enough.
