Lens and camera body(photoace)?

Question

will a 70-300mm sigma lens fit on a sony A200 and could i put a x2 teleconverter on it

Answer 1

Yes, you can as long as they are A-mount.

Answer 2

First you must determine what mount the Sigma lens is for. If its not for a Minolta Maxxum AF camera then it won't work. A professional camera store can tell you what mount your Sigma lens is made for.
