SIGMA

SIGMA 85mm f/1.4 DG DN Art L-Mount camera lens

SKU CH-MHP2-622K7

Large-aperture 85mm portrait lens with 11-blade diaphragm for smooth bokeh and fast autofocus on L-mount mirrorless cameras

  • Exceptional sharpness from 5 SLD and 1 aspherical elements
  • Smooth, rounded bokeh via 11-blade diaphragm
  • Fast, precise autofocus for stills and video
  • Dust- and splash-proof construction with hood lock
  • Compact, lightweight mirrorless design at 85mm f/1.4

Portrait prime for L-mount systems

The SIGMA 85mm f/1.4 DG DN Art is a large-aperture prime lens built for Leica L-mount mirrorless cameras. Its 85mm focal length and bright f/1.4 maximum aperture suit portrait photographers who want shallow depth of field and strong subject separation. Optical construction uses 5 SLD elements and one aspherical lens to control aberrations and deliver high resolving power across the frame.

Mirrorless-native design and handling

The lens is designed exclusively for mirrorless bodies, resulting in a compact and lightweight barrel that balances well on L-mount cameras. An 11-blade rounded diaphragm produces smooth, rounded bokeh highlights. A dust- and splash-proof structure protects internal mechanics during outdoor sessions. The package includes a lockable lens hood and a carrying case for transport protection.

Upgrade from slower or adapted glass

Photographers moving from variable-aperture zooms or adapted DSLR lenses gain a full stop of light at f/1.4 plus native autofocus speed tuned for mirrorless focus systems. The jump is worth it when consistent eye-detection AF, corner-to-corner sharpness wide open, and a weather-sealed build are required for professional portrait work. It does not serve shooters needing zoom versatility or focal lengths wider than 85mm.
