Ah, thanks guys, now I understand. The teleconverters bring your subject closer, the extension tubes bring you closer to the subject!
I have a canon 60D and my tamron lens is pretty pants to be fair. It worked better when I had my old canon 1000D but theres too much noise and fringing with the 60D (unless I just notice it more, nw I have a little more experience).
I think I now need to save for a Canon lens and a kenko teleconverter.The f stop loss I can cope with I think, but loss of autofocus might be an issue.Hope santa clause is good to me this year.....Thanks again for helping me understand.
