Will this - " VIVITAR/PENTAX K 2x TELE-CONVTR 'G' " work with my Sigma 70-300mm APO DG Macro lens and K100D.

I looked at the Lens Compatibility Chart @ http://www.pentaximaging.com/product...lity_chart.jsp
but it does not mention Tele-Convertors, K100D or 'G'

I know all old Pentax lens will work, but i don't know whether other brands ie Sigma and accessories will work or not, is there any list or info on how to find out ?

Any Advice Would be Appreciated.

I cant imagine auto focus would be possible unless the teleconverter has the autofocus drive, do you know if it has? Furthermore, I see the TC is described as just 'K' which might mean it has no extension of the electrical contacts effectively reducing your lens to the most simple 'K' type lens.
