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

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, which cannot be corrected by the camera.

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

High-speed AF for fast and convenient shooting

The SIGMA 50mm F1.4 DG DN Art is the first model in the Art product line to be developed exclusively for mirrorless full-frame cameras and uses the "HLA" (High-response Linear Actuator) linear motor. In addition, by using a single double-sided aspherical lens as the focusing 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 low-light photography, moving subjects, snapshots and video.

Powerful, yet slim and compact

When developing the SIGMA 50mm F1.4 DG DN Art, the focus was also on slimming down the lens barrel by reducing the weight of a focus lens and optimizing the layout of the lens unit. The aim was to achieve the "optimal size" for mirrorless systems without compromising the concept of "maximum optical performance" of SIGMA's Art line. With this lens, it has been possible to achieve both first-class performance and the size required for lightweight and mobile photographic tools.

Extensive functions and high build quality

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

All functions can be operated intuitively. The SIGMA 50mm F1.4 DG DN Art is dust and splash-proof and the front element 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 guaranteed by the reliable "Made in Japan" processing technology of the Aizu factory.
