Hey Everyone, Just wanting to know if you think I made a wise choice. I just picked up the older version Tamron 17-50mm 2.8 used for $300 shipped. I plan on having it replace my Nikon 18-105mm. I used the Nikon at a friends wedding this weekend and wasn't all that impressed with it compared to what I was getting with my Tamron 90mm 2.8. I was really liking the use of the shallow DOF for taking pictures of people. I'm hoping i want miss the extra range of the 18-105 and hoping the Image quality is superior on the 17-50mm. What do you all think? I was recently looking at my New England trip where I took 1200 pictures and used the 18-135mm lens a lot and noticed most of my images shot with that lens were in the 18-50 range so hopefully I won't miss the rest. And I do have the Nikon 70-300mm VR when I need more.
