Our take on the Sigma 56mm F1.4 DC DN Contemporary (Sony E)

The Sigma 56mm F1.4 DC DN Contemporary is a fast portrait prime for Sony E-mount APS-C cameras, giving roughly an 84mm full-frame equivalent field of view. Its f/1.4 aperture and 9-blade diaphragm make it a strong low-light and shallow-depth-of-field lens, and it is weather-sealed with internal focusing. At $454 at bhphotovideo.com as of November 4, 2026, it sits at the only new price listed, so there is no cheaper new option to compare against right now.
