SIGMA 50mm f/2 DG Contemporary L-Mount lens 350g

Standard full-frame lens

The Sigma 50mm f/2 DG Contemporary is a standard prime lens built for L-mount mirrorless cameras covering the full-frame format. Its 50mm focal length suits everyday photography from portraits to street scenes, and the f/2 maximum aperture allows shallow depth of field and low-light work. Weighing 350g (12.3 oz), it is designed for all-day carry without fatigue. Photographers wanting a lightweight, high-quality normal lens for L-mount systems will find it a practical choice.

Optical performance sustained

The lens uses one SLD glass element and three aspherical elements to control aberrations across the frame, maintaining sharpness and contrast during extended shooting sessions. A rounded nine-blade diaphragm produces smooth transitions between in-focus and out-of-focus areas, while the optical design minimises flare and ghosting even when pointing toward bright light sources. Autofocus remains responsive and accurate for continuous capture of moving subjects. The compact barrel does not extend during focusing, keeping balance consistent on the camera.

Compatibility check

Verify that your camera body uses the L-mount and supports full-frame coverage before ordering. The lens has no built-in stabilisation, so bodies with in-body stabilisation will provide shake reduction while those without will rely on shutter speed or a tripod. Ensure your camera can supply enough power for the autofocus motor during long sessions. Buyers needing a wider or longer focal length, a faster maximum aperture, or a lens with integrated stabilisation should look at other options.
