I am new to this forum as well as to Pentax or any (D)SLR world.

I has been for some months reading several forums trying to decide my camera, and finally has chosen K10D plus some Sigma Lenses.

While waiting for my system to come, I am looking for a way to get the max focal length possible with the less expense, so I am thinking of TCs, but being new to Pentax lens system I am not sure which one will be useful with every lens...

Could anybody explain me which TCs will manage lens aperture and try to AF on modern AF lenses, like kit one or the Sigmas I have chosen to buy (17-70, 70-300 APO, 105macro)? which one does manage Aperture but not even try to AF, or which ones will force me to Manual on everything? How can I manage the leneses in those cases?

Thanks for any hand you can give me.
