Ok, I currently own a T41 and the following lenses: 35 1.4 L / 85 1.8 / 100 2.8 L Macro / 70-200 f4L and I also own the 10-22 and 17-55 2.8 EF-S lenses. I am upgrading to the 5d Mark iii and I am thinking of getting the 24-70 v2 and the 16-35 L and selling my 2 EF-s lenses. I will still have a T4i as a second body but don't want lenses I can't use on both bodies. I am looking to start doing weddings, but currently shoot families and models with ease, my events are nice too but tougher to pull off with the rebel. Hence the upgrade to a FF with better ISO. Thoughts?
