I have a canon 60D and I'm going to be doing a road trip this summer, budget for new lens $2k. I'm looking for a walk around lens with a wide angle for landscapes and inside buildings. Here is some of the lenses I'm looking at, in particular order.
Canon 16-35 f/2.8
Canon 17-55mm f/2.8
Canon 24-70 f/2.8
Canon 24-105 f/4
I would like to hear some differing opinions and ideas please.
