What I want and will 1 day get is the 70-200L f2.8 IS. However is there anypoint in getting the Sigma 120-300 f2.8 aswell?
It would mainly be for motorsport's (Rally's, offroad racing)
Or should I be looking at the 70-200 and then the Sigma 50-500. Too many len's, too many choice's!
you could always put a 1.4 tcon on the canon and it would still cost less than the sigma.
The Sigma is quite popular amongst the sports guyshere, cadwell springs to mind...
