I remember the story. Nice Camera body you chose. I'm still using an original 5d. I think you made the right choice
Impressive shots with the cheaper Sigma. I never picked up a 24-70, just didn't feel I needed it. I do have the 17-40L, 70-200L, 100-400L, 50L. I want a new body to dabble in a little video but can't justify it.
