Probably a very silly question yet again!!
Why is it that it appears (other than kenko) you can mostly only use teleconverters with that manufacturers lenses, after all if you have a *Canon camera it will take Canon fit lenses from other manufacturer and they will autofocus on it.
If Sigma produce lenses that fit a Canon, the teleconverter fits a Canon body and a Canon fit lens, so why on earth can they not make them so that they can have a Canon lens fitted to them?
*Nikon users please read Nikon where I have typed Canon!!!!!
