You can get a good copy of the 18-55mm kit lens, for example, and its "best" isn't good enough for many people. There are plenty of lenses out there whose best quality doesn't pass muster for the discerning photographer. The Tamron 17-50 f/2.8 is one of those lenses that CAN pass with flying colors, but only if you get a good one. Tamron has had some quality control issues with that lens.
