SIGMA 35mm f/1.2 DG II Art camera lens L Mount 11-blade diaphragm

Prime lens for L-mount mirrorless

The Sigma 35mm f/1.2 DG II Art is a wide-aperture prime lens built for L-mount mirrorless cameras. It targets photographers who need shallow depth of field and strong low-light capability at a classic wide-angle focal length. The 11-blade rounded diaphragm maintains circular bokeh when stopped down. Buyers who need zoom versatility or a smaller maximum aperture should consider other options.

Wide aperture limits depth of field

At f/1.2 the plane of focus becomes extremely thin, so precise focus placement is critical for portraits or detail work. The optical design uses SLD glass, high refractive index elements and four double-sided aspheric lenses to correct axial chromatic aberration and sagittal coma flare across the frame. Stopping down reduces these effects but also reduces the light-gathering advantage that defines this lens.

Large front element needs care

The fast aperture requires a large front element, so a protective filter is advisable during transport and shooting. The lens barrel features a clickable aperture ring and an AFL button for direct control on compatible bodies. Autofocus relies on the camera body's focus system; calibration issues are rare but can appear on older firmware versions. Ensure the camera firmware is current before first use.
