Sigma 50mm f1.4 DG DN Art

Sigma 50mm f1.4 DG DN Lens | SIGMA 50mm for SONY

With exquisite optical performance and great power of expression as basic pillars, the Art line of SIGMA offers the highest levels of quality for creators. The SIGMA 50mm F1.4 DG DN | Art, a standard large aperture lens designed exclusively for full-frame mirrorless cameras, joins the select group of F1.4 lenses that have become bulwarks of the Art range.

Maintaining the concept of the 50mm F1.4 DG HSM | Original art, SIGMA has been rethought from the ground up what is truly important in a standard lens that will be used in a wide range of shooting situations. Equipped with the latest technological advances, this new model manages to offer the optimal size and high-speed AF demanded by mirrorless systems while maintaining the highest possible optical performance. In addition to the high brightness of F1.4 and the beautiful bokeh effect, various types of aberrations have been optimally harmonized in search of a homogeneous and balanced image quality throughout the frame, from the center to the edges of the frame.

Thanks to all this, this 'Art F1.4 50mm' is a truly versatile lens in terms of expressive performance and ease of use. A tool designed to help creators get their best results. Introducing the 50mm F1.4 DG DN | Art, the ideal standard lens of SIGMA.

1. F1.4 and Art range: uncompromising optical quality

Based on the latest optical design technology, this lens incorporates 14 elements organized into 11 groups, with 3 aspherical lenses and 1 SLD glass element. This composition makes it possible to effectively suppress various aberrations, such as astigmatism and field curvature, which cannot be corrected in the chamber. Despite the large aperture of F1.4, it has sought to take care of the performance at the edges of the image and has minimized the flash of sagittal coma, to the point that the lens can cope with challenging night scenes and starry sky, with demanding point light sources and using the maximum aperture. In addition to delivering crisp, color-blur-free image quality throughout the image circle, it's possible to take advantage of the natural beauty of big bokeh at F1.4 in any shot.

2. High-speed autofocus for agile and comfortable shooting

The SIGMA 50mm F1.4 DG DN | Art is the first lens in the Art line to incorporate the HLA (High-response Linear Actuator) linear motor. In addition, by using a single double-sided aspherical lens as the focusing element, AF is fast and quiet, with great subject-tracking performance despite the large F1.4 aperture. Thanks to this brightness and high-performance AF, the lens can be used in a wide variety of situations, from night photography to capturing moving subjects.

3. High performance in a compact and slim body

The development of the SIGMA 50mm F1.4 DG DN | Art has focused on styling the barrel by reducing the weight of a focusing lens and optimizing the optical design. It has sought to achieve the optimal size for a mirrorless system without compromising the philosophy of the highest possible optical performance that defines the Art line of SIGMA. That's why this lens delivers top-notch performance and the dimensions you'd expect from a lightweight, portable photo tool.

4. Wide range of functionalities and excellent construction

The lens barrel features a focus mode selector, a button to turn the aperture ring click on and off, a lock switch on the aperture ring to prevent unintentional actuation, and an AFL button to assign any camera function to it. Features all designed to make its operation totally intuitive. The lens is also equipped with a dust- and splash-resistant structure, and the front lens features a water- and oil-repellent coating, making it suitable for a wide shooting environment. It is compact, lightweight and easy to use, while delivering high build quality backed by SIGMA's solvent 'Made in Japan' production technology.
