I have been looking at different lens to put a new kit together?
The Canon 300mm f2.8 is just too much money for me?
So I looked at the Sigma APO f2.8 EX DG/HSM lens. Is this lens compatible with the Canon 1.4x II extender? I have read I think of somewhere of someonehaving problems with a Sigma lens and a Canon extender.
I would really appreciate your comments.
