The Sigma 24-70mm f/2.8 DG DN has enjoyed high demand since its announcement, but was it deserved? Lens Tips seems to think that it wasn’t due to a variety of flaws they found that while easy to correct with software shouldn’t exist when lenses like the Tamron 28-75mm f/2.8 Di III RXD FE offer superior performance for a lower price. The only advantage Sigma has against the Tamron is that it extends to 24mm according to Lens Tips, but is that a good enough reason to pick the Sigma over the Tamron?
