Sigma 50mm F1.4 DG DN Art Lens – Sony E-Mount

The New Benchmark in Standard Prime Lenses

The Sigma 50mm F1.4 DG DN Art is a next-generation standard prime lens designed specifically for full-frame Sony E-mount mirrorless cameras. Part of Sigma’s renowned Art line, it offers outstanding optical performance, ultra-fast autofocus, and a compact, robust design, making it an exceptional choice for professionals and enthusiasts alike.

Ideal for portraits, weddings, street, family, landscapes, and video, this versatile lens delivers the expressive power and detail that photographers demand from a true flagship optic.

Exceptional Optical Performance

Building on the legacy of the original Sigma 50mm F1.4 Art, this redesigned DG DN version achieves even higher levels of image quality, particularly at the edges of the frame.

• 14 elements in 11 groups, including 1 SLD (Special Low Dispersion) and 3 aspherical elements.

• Suppresses sagittal coma flare, astigmatism, and field curvature for unparalleled clarity.

• Smooth, natural bokeh with 11 rounded diaphragm blades for beautifully rendered backgrounds.

• Ultra-wide F1.4 aperture delivers razor-sharp results in low light, with stunning shallow depth of field for subject isolation.

Perfect for shooting wide open, the lens produces edge-to-edge sharpness and beautifully smooth out-of-focus areas, making it a go-to lens for expressive photography.

New High-Speed Autofocus System

The 50mm F1.4 DG DN Art is the first Sigma Art DG DN lens to feature the HLA (High-response Linear Actuator) motor, providing:

• Ultra-fast, near-silent AF with pinpoint accuracy.

• Reliable subject tracking even with moving subjects.

• Significant performance improvements for both stills and video.

Thanks to this new design, Sigma engineers were able to reduce the focusing group to a single double-sided aspherical element, resulting in a lighter, more responsive system that benefits both AF speed and optical performance.

Robust Yet Compact Design

Engineered to feel perfectly balanced on modern mirrorless cameras, the 50mm F1.4 DG DN Art is slimmer and lighter than its DSLR predecessor, weighing just 670g. Despite its reduced size, the lens maintains Sigma’s renowned Art-line build quality, with:

• Dust- and splash-resistant structure with sealing at the mount.

• Water- and oil-repellent coating on the front element.

• Thermally Stable Composite (TSC) outer barrel with aluminium inner barrel for reliable performance in varying temperatures.

• Professional-grade durability while remaining compact and travel-friendly.

Every Sigma lens is built at the company’s Aizu factory in Japan, with rigorous quality control and MTF testing to ensure precision and consistency.

Professional Features for Photographers & Videographers

Designed with working professionals in mind, the Sigma 50mm F1.4 DG DN Art includes a wide range of advanced features:

• Manual aperture ring with lock switch.

• Aperture Click switch – choose stepped or clickless aperture control, ideal for video.

• Customisable AFL button for user-defined functions (depending on camera body).

• Focus Mode switch for rapid AF/MF control.

• Smooth, rubberised focus ring for precise manual focusing.

• Petal-type lens hood with lock and rubber grip for secure, easy handling.

For L-Mount users, the lens is also compatible with the Sigma USB Dock, allowing firmware updates and customisation of focus ring response (linear or non-linear).
