The soon to be released Sigma 50mm f/1.4 DG HSM Art Lens has been tested against the already legendary Zeiss 55mm f/1.4 Otus
Xitek published the first comparison images of the new Sigma 50mm f/1.4 DG HSM Art lens against three other lenses: Sony Planar T* 50mm F/1.4 ZA SSM, the Nikon Nikkor AF-S 58mm f/1.4G, and the Otus Zeiss 55mm f/1.4 Otus
Sigma has already mentioned that they are confident about the new 50mm Art lens surpassing the current Nikon and Canon lenses, instead targeting the Otus Zeiss 55mm f/1.4. The comparisons we see confirms this statement, Sigma lens looks head to head with the Otus and better than the Nikon and the Sony Planar T* 50mm F/1.4 ZA SSM.
