After much rumour and leaking, Sigma has now officially announced the new Sigma 50mm f/1.4 DG DN Art series lens for mirrorless cameras. Coming specifically for Sony E and Leica L mounts, the new lens sees a complete redesign over the old 50mm f/1.4 DG HSM Art series lens for DSLRs. Like its DSLR predecessor, it’s designed for full-frame cameras, and boasts “outstanding edge-to-edge imaging performance”.
It’s also the first lens in Sigma’s Art series of lenses to sport Sigma’s new High-response Linear Actuator (HLA) autofocus motor. This system was first introduced in the recently released 60-600mm DG DN OS Sports lens and allows the 50mm f/1.4 DG DN Art to achieve “swift and silent autofocus” for both stills and video.
