When Sigma released its 50mm F1.4 DG HSM | Art for full-frame DSLRs back in 2014, it redefined our expectations of how large-aperture primes could perform. By using a large, complex optical design, it delivered stunning levels of sharpness, and rapidly became considered a modern classic. Now we have a DN successor that’s specifically designed for mirrorless cameras, the Sigma 50mm F1.4 DG DN | Art. It’s fair to say that expectations are high.
Compared to its illustrious predecessor, the DN version sports an all-new design with completely revamped optics. Physically it’s lighter but a little longer, and it now boasts an aperture-control ring and weather-sealed construction. It’s available in Sony E and L mounts.
With its 50mm focal length, this is a general-purpose optic that’s suited to a wide range of subjects. Its f/1.4 aperture makes it particularly well suited to shooting in low light, or in situations when you wish to isolate your subject against a blurred background.
