The Sigma 50mm f/1.4 DG HSM Art is more than a simple refresh of the previous version of the lens. It is a completely new designed lens, with a performance that Sigma claims is on the same level as the Zeiss Otus 55mm f/1.4. A bold claim, but given Sigma’s recently released, awesome lenses, this is a claim we should take seriously.
[...] the most impressive information we gleaned? When discussing their goals of image quality and sharpness for the lens, Sigma mentioned they’re confident they’ll surpass competitive products from Canon and Nikon and are instead gunning for Zeiss’s new 55mm Otus lens. It’s a serious claim. The Zeiss 55mm f/1.4 Otus lens — with its $4000 price tag — is squarely aimed at high-end professional shooting such as fashion, advertising and editorial work.
