24-70 f/2.8 ii is a very sharp lens only when we use with tripod. I have been using this lens with 5DMIV. I have accepted the truth when the lens does not have IS and the body does not have IS either tripod is a must. If one is okay to use the tripod this lens will not disappoint.

The previous 24-70/2.8 L feels much, much better made. The original lens is all metal, while this one feels mostly like plastic. The front section of this new lens is all plastic, and if you try to wiggle it when extended to 70mm, a little bit of wiggle is normal.
