Pick the Sigma 70-200mm f/2.8 if you need a versatile telephoto zoom for portraits, events, or sports at a lower price. The Tamron 15-30mm f/2.8 stays the better choice if you prioritize ultra-wide-angle coverage for landscapes, architecture, or tight spaces—and are willing to pay the premium. Choose based on focal length needs, not just aperture or price.
