As long as the converter is EF, it wil mount to the 70-300, but as the max aperture will exceed f8 you will have to focus manually as I'm sure AF won't work.
+1 on Dave's comment, but as well as losing autofocus I'm not sure what the results would be like, the Sigma 70-300 isn't a brilliant lens to start with and a teleconverter isn't going to help things.
thankyou all for info i will continue to investigate and report back if i find in my favour, just would like to say that i found the sigma 70-300 DL to be to be a very good lens, its comparable if not better than my cannon 50-250 which punches well above its cost, but we all have different idea's as to buying a lens, for our own situation. thank you again davesnr,
