Sigma 50mm f1.4 DG DN (A) L-Mount

The "Art F1.4" standard with uncompromising optical performance

Based on the latest optical design technology, the lens contains 14 elements in 11 groups, including 3 aspherical lenses and 1 SLD glass element. This optical design effectively eliminates various aberrations, such as astigmatism and field curvature, that cannot be corrected by the camera.

Despite the large aperture of F1.4, imaging performance has not been neglected even at the edges of the image and sagittal coma has been minimized to such an extent that this lens can withstand astro and low-light photography with challenging subjects and point light sources at wide open apertures. In addition to a clear image without color blur across the entire image circle, the natural, soft bokeh comes into its own at F1.4

High-speed AF for fast and comfortable shooting

SIGMA 50mm F1.4 DG DN Art is the first model in the Art product line developed exclusively for mirrorless full-frame cameras and uses the "HLA" linear motor (High-response Linear Actuator). In addition, by using a single double-sided aspherical lens as the focus element, the lens offers fast and quiet focusing and high tracking performance despite its large aperture. With a maximum aperture of F1.4 and a powerful AF system, the lens can be used in a variety of situations, including shooting in low light, capturing moving subjects, snapshots, and even video

Powerful, yet slim and compact

development of the SIGMA 50mm F1.4 DG DN Art also focused on slimming down the lens barrel by reducing the weight of a focus lens and optimizing the layout of the lens unit. The goal was to achieve the "optimal size" for mirrorless systems without compromising the "maximum optical performance" concept of SIGMA's Art line. This lens has succeeded in achieving both top-notch performance and the size required for lightweight and mobile photographic tools

Extensive features and high build quality

The lens is extensively equipped. It offers a focus mode switch, an aperture ring click switch, for turning the click on and off when selecting aperture via aperture ring, and an aperture ring lock switch, which prevents unintentional adjustment of the aperture ring. Furthermore, it has an AFL button that can be assigned to any camera function depending on the camera model, and

all functions can be operated intuitively

The SIGMA 50mm F1.4 DG DN Art is dust- and splash-proof, and the front lens of the lens has a water- and oil-repellent coating, making it suitable for challenging shooting environments. The lens is compact, lightweight, and easy to use, while offering the high build quality provided by the Aizu factory's reliable "Made in Japan" processing technology
