Focused on sophisticated optical performance, Sigma reexamined the original Sigma ART 50mm f/1.4 DG HSM and incorporated all the latest technologies. This lens exemplifies theperfect balance between optimum size and high-speed AF required for today’s mirrorlesssystems, while achieving the highest-class optical performance. In addition to the brightnessof the large F1.4 aperture and the large, beautiful bokeh effect, various aberrations havebeen optimally reduced in pursuit of uniform and balanced image quality throughout theentire image range, from the center to the edges of the frame. The result is the new “ART 50mm f/1.4,” 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.

The “ART f/1.4” standard with uncompromising optical performance

Based on the latest optical design technology, the lens incorporates 14 elements in 11 groups, with 3 aspherical lenses and 1 SLDglass element. The lens effectively suppresses various aberrations such as astigmatism and field curvature, which cannot be correctedin-camera. Despite the large aperture of f/1.4, the image formation performance on the periphery of the image has been pursued andsagittal coma flare has been minimized to the extent that the lens can withstand even challenging star and night scenes, with demandingpoint light source imaging, from wide open. In addition to clear image quality with no color blur throughout the entire image circle, thelarge, natural bokeh beauty of f/1.4 can be fully utilized in photography.

High-speed AF for nimble and comfortable shooting

The Sigma ART 50mm f/1.4 DG DN is the first in the Art line exclusively designed for full-frame mirrorless lenses to adopt the “HLA”linear motor (High-response Linear Actuator) . In addition, by using a single double-sided aspheric lens as the focus lens, the lensoffers fast and quiet focusing and high tracking performance despite its large aperture. With a maximum aperture of f/1.4 and a high-performance AF system, the lens can be used in a variety of situations, including shooting in dark places, shooting moving subjects,snapshots, and even video.

High performance, yet slim and compact

The development of the Sigma ART 50mm f/1.4 DG DN was focused on slimming down the lens barrel by reducing the weight of afocus lens and optimizing the lens unit layout, to pursue the “optimum size” for mirrorless systems without compromising the “maximumemphasis on optical performance” concept of SIGMA’s Art line. This lens has succeeded in achieving both top-class performance, andthe size required for a light and mobile photographic tool

Full range of functions and high build quality

The lens barrel is equipped with a Focus Mode switch, an Aperture ring click switch to turn the click on and off, an Aperture ring lockswitch to prevent unintended operation, and an AFL button to assign any function from the camera. These features are designed forintuitive operation during shooting. The lens is equipped with a dust and splash resistant structure, and the front element of the lensis applied with a water and oil repellent coating, making it suitable for a wide range of shooting environments. The lens is compact,lightweight, and easy to use, while at the same time ensuring high build quality assured by the Aizu factory’s reliable processingtechnology of “Made in Japan”.
