Description — Sigma 50mm f/1.4 DG DN
The Sigma 50mm F1.4 DG DN Art is a full-frame mirrorless-native prime lens with a maximum aperture of f/1.4, sitting in the standard focal length range at 50mm. It is available in Sony E-Mount and L-Mount, making it a practical option for photographers shooting across two of the most widely adopted mirrorless platforms. The lens supports autofocus and manual focus, offering control flexibility for a range of shooting scenarios from fast-moving subjects to deliberate, precise manual work.
A 77mm filter thread allows compatibility with common filter accessories. At 670g, the lens has a solid, substantial build consistent with its aperture class. There is no image stabilization on board, so IBIS-equipped bodies will be important for those shooting in demanding conditions.
As part of Sigma's Art line, the 50mm F1.4 DG DN is designed from the ground up for mirrorless systems — not an adapted DSLR design — which informs its overall form factor and autofocus integration with compatible mirrorless bodies.
