as i understand it, if you have Nikon AF-S or Sigma HSM internal motorised AF lenses than yes the AF should continue to work for most of these lenses, however, for non internal focusing motor lenses it will not work ,
and the only HSM sigma from the list you provided was the 100-300 ( and the 180 prime ) for the more resonable priced kit ( slower than F2.8 )
like i said, i'm not saying the pix will be bad or anything like that at all, but compatability using the tele-converters is really limited to exclusive fast lenses, and the combo is not cheap when you think just the converter starts at over £100.....
just my thoughts
