Sigma launches SIGMA 50mm f1/2 DG DN I Art lens

SIGMA Corp. of America announced SIGMA 50mm F1.2 DG DN | Art lens, a remarkably compact, ultra-fast standard prime lens for full-frame mirrorless camera systems. Offered in L-Mount and Sony E-mount versions, the lens will be available on April 18, 2024 at a retail price of $1,399 through authorized retail partners.

The F1.2 maximum aperture allows photographers to actively take advantage of the large bokeh effect and to shoot handheld with a wide aperture in low-light situations such as indoors and evening scenes, the company says. Thanks to the excellent correction of various aberrations such as spherical aberration, sagittal coma flare, and axial chromatic aberration, along with SIGMA’s first 13-blade rounded diaphragm, which maintains a circular bokeh effect even when the aperture is stopped down, this lens delivers beautiful imaging characteristics.

Dual HLA-driven floating focusing, with one group near the front of the lens and one group near the back, provides stable optical performance from close to distant focus. The design also minimizes focus breathing, with very little change of the angle of view as focal distance changes, which is helpful for video capture. The dual floating HLA autofocus achieves focus smoothly, swiftly and silently for both still and video, and the manual focus ring can be assigned to be linear or non-linear response on compatible L-Mount cameras.

Despite the fast aperture, the SIGMA 50mm F1.2 DG DN | Art lens has the lightest weight in its class, and is 30% smaller than the SIGMA 35mm F1.2 DG DN | Art lens, teh company says. It is very similar in size and weight to the SIGMA 50mm F1.4 DG DN | Art lens, which was achieved in part by streamlining the optical system.As a DG DN Art lens designed specifically for full-frame mirrorless camera systems, the SIGMA 50mm F1.2 DG DN | Art is built with dust and splash-resistant structure, water and oil-repellent coating on the front lens element, and durable brass bayonet mount; along with click/de-click and lockable aperture ring, an AFL button, and AF/MF switch.
