Non Nikkor TC on 35mm f/1.8G AF-S DX

[Rif]

Hi all
Not entirely sure if I'm supposed to post this in the beginner area......
I'm looking at buying a D7000 with the above lens.
I know I'd need a step down to even fit my 58mm Sony teleconverter but I'm wondering if it'll even work on
the Nikon combo.
Any thoughts.
The D7000 purchase would break the bank at the mo so I'm hoping the TC would offer a bit of scope
till I could afford some more glass.
I guess I'm asking if the D7000, lens and my Sony teleconverter will be able to focus (manual or auto focus)?
The converters I have are 58mm threaded that attatch to the filter end of a lens and not between the lens and body.
They are Sony HG lenses (high grade) and include:
VCL-HG1758 (X2) and VCL-HGD1758 (X1.7) and VCL-HDG0758 (X0.7)
