First off, thanks to everyone for guiding me to this great lens!
The Tamron 28-75 f2.8 XR Di arrived today so I quickly mounted it to my trusty DS for some tests.
Build - Solid and heavy but comfortable. When mounted, it appears to dwarf my DS but I like the overall feel. It looked smaller in photos published all over the internet so I was a little surprised when it arrived. Excellent fit and finish and the lens exudes a professional appearance.
Performance - pretty good AF focus speeds throughout the entire zoom range and fairly quiet IF. The large soft rubberized rings provide precise control over focus and zoom. I like the fact that you can lock the zoom barrel so it doesn't accidentally slide out when you have the camera around your neck.
IQ - Very, very good! Sharp results at f2.8 and very sharp when stopped down to f4.0 - 5.6 for 28mm to 50mm range. At 75 mm, sharpest results were observed at f5.6 - 8.0. The f2.8 constant aperture is really sweet because it yields nice shallow DOF results throughout the entire zoom range (if so desired). This lens rivals my primes and so it's a welcome addition to my camera bag.
