Verdict
Pick the Sigma 17-50mm if you need a fast, wide-to-portrait zoom for low light or indoor shooting. Choose the Tamron 70-300mm if telephoto reach for distant subjects is your priority and you can accept the slower aperture. The Sigma stays the better choice if weight or close-up versatility matters; the Tamron wins if budget and long-range flexibility are equal.
