Sigma 50mm f/1.4 DG DN Art Lens: The Ultimate Large-Aperture Standard Prime

Achieve artistic perfection with the Sigma 50mm f/1.4 DG DN Art (A023), a flagship standard prime lens re-engineered from the ground up exclusively for full-frame mirrorless cameras. Replacing its legendary DSLR predecessor, this modern optical masterpiece completely balances a massive, light-gathering f/1.4 aperture with a sleeker, lighter physical profile. Built for photographers and filmmakers who refuse to compromise on image quality, it delivers staggering edge-to-edge resolution, near-zero optical distortion, and the creamy, dreamlike background isolation that defines Sigma’s elite Art line.

Sigma 50mm f/1.4 DG DN Art Key Product Features

• Ultra-Bright f/1.4 Aperture: Offers exceptional low-light capabilities and an incredibly shallow depth of field, allowing you to easily isolate subjects from busy backgrounds for professional portraiture.

• Next-Gen HLA Autofocus Motor: The first mirrorless Art-line lens to implement Sigma’s High-response Linear Actuator (HLA) motor. It delivers blazing-fast, silent, and flawlessly accurate tracking for moving subjects and high-framerate video.

• Uncompromising Art-Line Optics: Combines 14 elements in 11 groups—including three high-precision aspherical elements and one SLD glass element—to aggressively eliminate sagittal coma flare, chromatic aberrations, and field curvature.

• Cinematic 11-Blade Diaphragm: Built with an unusual 11-blade rounded diaphragm that retains perfectly circular, buttery-smooth bokeh highlights even when stopped down slightly.

• Pro-Grade Video Features: Outfitted with a physical aperture ring that includes both a “de-click” switch for silent, smooth aperture transitions during filming and a safety ring lock switch to prevent accidental shifts.

• Customizable AFL Button: Features an integrated Focus Mode switch and an adjustable Autofocus Lock (AFL) button on the lens barrel that can be reassigned to various helper functions via the camera menu.

• Rigorous Weather Proofing: Complete dust- and splash-resistant construction with interior seals across all joints, paired with a water- and oil-repellent coating on the exposed front lens glass.
