Description and Reviews

Key Take-Aways:

The Sigma 50mm f/1.4 DG DN Art is a fast standard prime redesigned for mirrorless, offering an f/1.4 aperture, 670g weight, and a balance of portability and pro features. Professional reviews highlight its excellent sharpness, smooth bokeh, fast and reliable autofocus, and strong build quality, with downsides including moderate vignetting at wide apertures, some longitudinal chromatic aberration, and competition from lighter or more affordable 50mm options. As of Sep 14 2025, user sentiment is very positive, with many considering it a strong value choice that delivers high image quality without the premium cost of first-party lenses.

From Sigma:

“ART F1.4 50MM” FOR MIRRORLESS. THE NEW STANDARD FOR ARTISTIC EXPRESSION, PRESENTED BY Sigma.

The highest level of expressive performance, high-speed AF, and compactness―all combined in perfection. The new standard for “Art F1.4” large-aperture standard prime.

Designed with a focus on sophisticated optical performance and tremendous expressive power, Sigma’s Art line delivers high-level artistic quality. The newest addition to the F1.4 series, which has become synonymous with the Art line, is the Sigma 50mm F1.4 DG DN | Art, a large-aperture standard lens designed exclusively for full-frame mirrorless cameras. While retaining the concept of the original Sigma 50mm F1.4 DG HSM | Art that defined the reputation of the Art F1.4 series, Sigma has reexamined from the very beginning what is truly important in a standard lens used in a wide range of shooting situations. By incorporating all the latest technologies, this lens has achieved a high degree of compatibility between the optimum size and high-speed AF required for today’s mirrorless systems, while maintaining the highest-class optical performance.

In addition to the brightness of the large F1.4 aperture and the large, beautiful bokeh effect, various aberrations have been optimally balanced in pursuit of uniform and balanced image quality throughout the entire image range, from the center to the edges of the frame. The result is the new “Art F1.4 50mm,” a lens that is truly all-around capable in terms of expressive performance, maneuverability, and usability, and is designed to help photographers create their best work. Introducing the 50mm F1.4 DG DN | Art, Sigma’s ideal “standard” lens.
