do i need to bring my camera down to test before buying?
That is recommended by users here alike. Sometime lens are not made perfect down to the optical quality so it's best to test it with your body to see if there's any defect.
For the Tamron 17-50mm there seems to be an issue of some units facing front/back focus(where the lens focus front/back where it's suppose to instead) so i do advice bringing down your body.
