SIGMA

SIGMA 50mm f/1.2 DG DN Art L-Mount camera lens, Black

SKU CH-DH2M-KTBK9

Full-frame 50mm f/1.2 lens with HLA autofocus, four aspherical elements, 13-blade rounded diaphragm, de-clickable aperture ring and dust- and splash-resistant build

  • ColorBlack
  • f/1.2 maximum aperture for extreme low-light control
  • 13-blade rounded diaphragm creates smooth circular bokeh
  • HLA linear actuator delivers fast precise autofocus
  • four aspherical elements suppress aberrations across the frame
  • de-clickable aperture ring enables silent iris transitions

Lightweight f/1.2 Art lens for L-Mount

This full-frame prime is the lightest in its class and delivers high resolving power from f/1.2 through f/16 across the entire focus range. Its compact body strips the design to bare essentials while keeping professional-grade functions. The wide maximum aperture creates large, beautiful bokeh suited to portrait and low-light work.

Sustained optical performance

High resolution is maintained from maximum aperture to the full focus range without the drop-off often seen at wider settings. The HLA autofocus motor provides fast, precise drive with reduced internal volume and consistent thrust during extended shooting. Super Multilayer Coating controls flare and ghosting when the lens is pushed hard in bright or backlit conditions.

Straightforward L-Mount installation

The lens mounts directly to any Leica L-Mount body with no adapter required. A de-clickable aperture ring lets video shooters pull iris smoothly, while the 13-blade rounded diaphragm stays circular when stopped down. Dust- and splash-resistant construction protects the mechanism, though the front element remains exposed without a built-in hood.

Questions about this item

Does the lens get hot or draw much power during all-day shooting?

The lens is passive and draws no power itself; the High-response Linear Actuator runs from the camera body, so heat and power depend on the camera you use.

What must I already own for this lens to work?

You need a camera body with the L-Mount bayonet to attach and operate the 50mm f/1.2 DG DN Art.

How does it behave on an older L-Mount body I might keep?

It mounts natively on any L-Mount body; autofocus and aperture control function normally, while the 13-blade diaphragm and Super Multilayer Coating deliver the same optical character.
