Hello OiCecil,


We use both the 24-70 & 70-200 2.8 and find them to be quite up to the demands we put on them. I hope you will not be disappointed with either should you purchase a 70-200 2.8. Both lens are used on 1DMK11 bodies.


We find on our Xti/grip combo that each of the lens's render the combination to front heavy for extended shooting.


Have fun and be safe...
