It was just a few months ago that Sigma released their new 50mm F1.4 DG DN | Art lens overseas, which is priced at $849. Currently, the National Bank version of this lens is on the market, with a starting price of 5,999 CNY. This lens is compatible with Sony E-mounts and L-mounts (i.e. Sigma, Leica, Panasonic three alliances).
SIGMA 50mm F1.4 DG DN 丨 Art is a standard prime lens specially designed to be used with mirrorless cameras with full-frame sensors. The size and weight of this device is about 670g, it has a diameter of 78.2mm, and it has a length of 109.5mm / 111.5mm. Among the features of this lens is that it has a 45cm minimum focus distance, supports L mount and E mount, and it has a 72mm filter size.
In terms of parameters, this lens is based on Sigma’s latest optical technology and integrates 11 groups of 14 lenses, including 3 aspherical lenses and one SLD special low dispersion lens, which essentially suppresses various aberrations, like astigmatism that cannot be corrected in camera and curvature of field that cannot be corrected in camera.

It is important to note that even when the aperture is fully opened, the imaging quality at the edge of the image remains guaranteed, and the sagittal aberration is minimized, which means that the lens can even handle harsh point light source imaging scenes such as starry skies and nights, which are quite challenging.
Sigma said that the new SIGMA 50mm F1.4 DG DN丨Art is the first full-frame mirrorless lens in the Art series to adopt the “HLA” high-speed linear motor. The focusing lens is an SLD special ultra-low dispersion double-sided aspherical lens, regardless of the fact that the large aperture lens is also capable of providing fast and quiet focusing, as well as tracking focusing capabilities at high speeds.
As a result of its maximum aperture and high-speed autofocus system, the lens is able to be used in a variety of shooting situations, including low-light conditions, shooting moving objects, taking snapshots,
