After almost three years with my faithful Sigma 500 f4.5 EX APO HSM it is now to time to upgrade to Canon. I am still not sure whether to buy the 500mm or to take the plunge and invest in its bigger brother. I've looked at the spec of both of them and still not sure which one to to order.
So are there any users out there of the 600mm who have used the 500mm and have now got the bigger lens?
Any info greatly received
Cheers
