Pick the Sigma 17-70mm if you need a versatile walk-around zoom with a wider-angle start, brighter aperture at the short end, and macro capability at a lower price. Choose the Tamron 70-200mm if your priority is telephoto reach, constant f/2.8 aperture, and macro performance at the long end, accepting the higher cost and heavier weight. The Sigma stays the better choice for everyday shooting and tighter budgets, while the Tamron remains ideal for subjects requiring longer focal lengths.
