I've tried to avoid tele-converters so I'm not much help...
But I gotta ask... Why bother when you have the Sigma 50-500?

I ride a triumph sprint GT and it's not always possible to carry the big stuff, and i am of the opinion that the 300 + converter would still be sharper than the sigma 50-500.

Does anyone use this converter? am seeking advise on its use with the pentax 300 f4and tamron 70-200 2.8
Tamron 1.4x Pz-AF MC4 is probably the best bet if you can find one s/h, they can be quite pricey. Alternatively the Kenko (Teleplus) 1.5x SHQ and 1.7x SHQ give very good results.Does anyone use this converter? am seeking advise on its use with the pentax 300 f4and tamron 70-200 2.8

£900 for a big Sigma versus £90 for an adapter from Microglobe.
It would be very surprising if there wasn't a big difference.
Same goes for having the money for those nice SDM lenses or a K5 over my KR
I think i'll stick to cropping where necessary and quietly sneaking up on the wildlife!

Ok, just making sure it wasnt screw drive or manual focus .. SDM limits the converter considerably.
If you dont mind a bit of manual tweaking focus wise then the 1.7x is the best quality imo but if you want full af then one that John listed will work.
I have a Kenko 1.5x SHQ and it works fine with SDM but it does lack the little bit of extra IQ the 1.7x gives (as well as the slight increase in length)

A 300mm with decent teleconverter can outperform the 50-500mm by some margin, I use a F* 300mm and 1.7x Pentax converter and it is better than my Bigma.
+1, the DA*300 + decent 1.4x, 1.5x or 1.7x TC will outperform a Bigma in terms of IQ.Which 300mm f4?

I would say the same as Mike, I have also settled on the DA300 plus Pentax 1.7x.
