Sigma is a company that makes some questionable choices. We’ll never discount their image quality. But the rest of the package is just always odd. Take the new Sigma 28-70mm F2.8 DG DN Contemporary. For the most part, they say it’s an Art series lens. But the big differences are with the build quality and the focal range. In fact, the Sigma 24-70mm f2.8 DG DN Art is around double the weight. For what it’s worth, we also really liked that lens and gave it a five-star review. But the Sigma 28-70mm F2.8 DG DN Contemporary is claiming similar image quality performance at a few hundred bucks less at $899. To me, it seems like a diet Art lens. And in the grand scheme, we wonder if it’s a disposable option.
