Sigma 85mm F1.4 DG DN Art Lens for Mirrorless Cameras, L-Mount, Fast AF, Perfect for Portraits

The Sigma 85mm F1.4 DG DN | Art, model A020, is a full-frame mirrorless prime engineered for portrait and hybrid creators who demand f/1.4 performance in a compact package. With a large-diameter optical design, five SLD elements, an aspherical element, and high refractive index glass, the lens delivers high resolving power across the frame while producing a distinctive subject separation and bokeh.

Designed for Leica L-mount systems and compatible mirrorless bodies, the lens blends professional optical correction, an 11-blade rounded diaphragm, and a mirrorless-optimized STM autofocus to address common portrait and video pain points, including low-light AF reliability, edge sharpness at wide apertures, and focus breathing control for cinematic use.
