Pretty much most things I say But I'm selling my 11-16. Guy is like I really want it, but I wish it had a little more reach like the 12-24. I once said this. I now realize how stupid it was. Sharpness and 2.8 > 17-24 on a wide. I also bashed Tamron before I owned one. Went by what people said and horror stories. I now own the 17-50 and it's my favorite lens. Absolutely love that lens.
