The gold standard of fast-aperture standard primes
The SIGMA 50mm F1.4 DG DN | Art sets a new benchmark for image quality, speed and handling in a standard prime lens. Designed exclusively for full-frame mirrorless cameras, this versatile optic combines a classic focal length with a bright F1.4 aperture, making it the ideal choice for portraits, weddings, street photography, landscapes and travel.
Delivering outstanding sharpness and clarity across the entire frame—even on the highest-resolution sensors—the 50mm F1.4 DG DN | Art produces images rich in detail, character and atmosphere. Its smooth, refined bokeh allows for stunning subject separation and beautiful background blur, perfect for working with a shallow depth-of-field.
At the heart of its performance is SIGMA''s cutting-edge HLA (High-response Linear Actuator) motor, providing lightning-fast, accurate and near-silent autofocus for both stills and video. Thoughtfully designed for the modern hybrid creator, the lens also includes a manual aperture ring with click/de-click and lock functions, a customisable AFL button, and a lockable petal-style hood. Despite its professional-grade construction, it remains comfortably portable, weighing just 670g.
Outstanding build quality
Crafted with SIGMA''s renowned Art-line precision, the 50mm F1.4 DG DN | Art offers an exceptional combination of durability, balance and tactile refinement. The outer barrel is made from Thermally Stable Composite (TSC), a high-grade polycarbonate that is both strong and lightweight. Because TSC has a thermal expansion rate similar to aluminium, the internal and external components maintain perfect alignment across a wide temperature range—ensuring consistent performance in any environment.
The rubberised focus ring provides smooth, precise manual control, while the lens''s internal focusing system ensures that it never changes length, maintaining perfect balance for gimbal or handheld use.
The aperture ring can be operated directly on the lens for intuitive exposure control or set to Auto for in-camera adjustment. The robust, lockable lens hood features a rubber grip for quick and easy attachment, reducing flare and ghosting in bright conditions while protecting the front element.
A durable brass mount surrounded by a weather-sealing gasket provides an extra layer of protection against dust and moisture, ensuring reliability in challenging outdoor environments.
Professional feature-set
Designed with the working photographer in mind, the 50mm F1.4 DG DN | Art includes a comprehensive array of controls: an AF/MF switch, a customisable AFL button, and dedicated click/de-click and lock switches for the aperture ring. These allow seamless transition between stills and video workflows.
The click/de-click switch provides smooth, continuous aperture adjustment—perfect for filmmakers—while the lock switch prevents accidental movement between Auto and Manual settings during shooting. Every detail has been engineered for precision and control.
High-speed HLA focusing motor
The SIGMA 50mm F1.4 DG DN | Art was one of the first lenses to feature SIGMA''s powerful High-response Linear Actuator (HLA) motor. Offering greater torque than traditional stepping motors, it enables fast, accurate and virtually silent autofocus, even with complex focus tracking.
Because the HLA can move larger, heavier focus groups with ease, it allows for more advanced optical designs—resulting in sharper images, improved aberration control and outstanding performance across the frame.
High-performance optics
The optical design of the 50mm F1.4 DG DN | Art consists of 14 elements in 11 groups, including three aspherical and one SLD (Special Low Dispersion) element. This sophisticated configuration minimises chromatic aberration, distortion and vignetting, delivering edge-to-edge sharpness and stunning contrast even at the widest apertures.
Advanced multi-layer coatings further suppress flare and ghosting, ensuring rich colour and deep blacks when shooting in bright or backlit conditions. The result is a lens that performs flawlessly in any lighting scenario.
Perfect for portraits
With its bright F1.4 aperture, the 50mm DG DN | Art produces creamy, beautifully rendered bokeh that enhances subject separation and creates a natural, three-dimensional look. The 50mm focal length delivers a flattering perspective for portraits and waist-up compositions, while its wide aperture captures four times more light than an F2.8 lens—reducing the risk of camera shake and motion blur in low-light conditions.
Whether you''re capturing intimate portraits, cinematic video or creative street scenes, the SIGMA 50mm F1.4 DG DN | Art remains the definitive fast-aperture standard prime—built for performance, precision and artistry.
