Ok, I had a 24-70 Nikon f2.8 borrowed for a few weeks and fell in love with it. I saved enough to purchase that lens with a 85mm f1.8. This is pretty much the range I shoot nowadays and should suit me well enough. Since it is a lot of cash to part with I am naturally second guessing it. Are there alternatives that give me the amazing quality of these 2 lenses in a similar package? I read about the sigma 24-70 but it has a 82mm filter thread!!.. And I really want the 24mm and not 28 from the Tamron. If this seems like the only combination that covers this range, I will just go for it..
