Anyone got any suggestions as to what to buy? Preferred choice is 1.4x but will consider a 2x
I don't want to spend "Canon money".

Chris, I have the Sigma 1.4x and it works fine. I was told that you have to use one the same make as your lens, but I don't know how true that is. I've heard that the 2x is not as good.
I bought mine from Jacobs (not sure if you have them over there) and it cost me about £140.
Thanks Diane, does it affect the Auto-focus system?
