Discover a world of creative possibilities
Unleash your vision with the SIGMA 50mm F1.2 DG DN | Art, designed for full-frame L-Mount and Sony E-mount mirrorless systems. This fast, high-performance prime delivers stunning depth-of-field control, ultra-sharp detail and exceptional bokeh—all in a lightweight, portable body. Ideal for portraits, low-light landscapes, street scenes and expressive travel photography, it combines a bright F1.2 aperture, dual HLA motors and precisely engineered optics to ensure rapid, reliable performance for both stills and video. Weighing just 745g*, this is the lightest F1.2 lens in its class, making it the perfect companion for handheld or gimbal-based shooting.
Bright F1.2 aperture with exceptional optical performance
At the heart of the SIGMA 50mm F1.2 DG DN | Art lies a sophisticated optical design built around 13 rounded diaphragm blades—a first for SIGMA. This configuration produces smooth, circular bokeh and exquisite background separation, even wide open at F1.2. Every frame is rendered with exceptional sharpness, contrast and colour fidelity, while aberrations such as sagittal coma flare, axial chromatic aberration and double-line bokeh are meticulously corrected for pristine image quality.
A floating focus system ensures outstanding performance at all distances, maintaining clarity and contrast from close-up subjects to infinity. Focus breathing is also heavily suppressed, making the lens ideal for cinematic video work and smooth focus transitions.
SIGMA''s first 13-blade diaphragm design
The newly developed 13-blade circular aperture maintains a perfectly round shape at wide apertures, allowing photographers to create beautifully soft and uniform out-of-focus areas. This design delivers exceptionally smooth bokeh and superior subject separation—ideal for portraits, still life and artistic close-ups shot at F1.2.
Minimised focus breathing, flare and ghosting
The optical layout and focus group arrangement have been carefully optimised to significantly reduce focus breathing and maintain natural focus transitions during video recording. SIGMA''s advanced coatings effectively suppress flare and ghosting, ensuring rich contrast and clarity even when shooting in strong backlight or challenging lighting conditions.
Compact, lightweight design for any scenario
Despite its ultra-wide aperture, the SIGMA 50mm F1.2 DG DN | Art has been engineered for exceptional portability. Through advanced optical design and cutting-edge manufacturing at SIGMA''s Aizu facility in Japan, engineers have reduced the size of individual glass elements while maintaining optical integrity. The result is a 30% lighter build than the 35mm F1.2 DG DN | Art, without any compromise in performance.
This balance of power and portability makes it the ultimate everyday lens for professionals and enthusiasts alike.
Precision focusing with dual HLA motors
The 50mm F1.2 DG DN | Art features a floating focus system driven by dual HLA (High-response Linear Actuator) motors. These newly developed motors provide outstanding thrust while being slimmer and lighter than previous generations—achieving approximately 25% thinner and 44% lighter focus units. The result is autofocus that is fast, precise and virtually silent, making it perfect for stills, video and hybrid workflows.
Professional feature set
A range of refinements ensures the 50mm F1.2 DG DN | Art performs flawlessly in any shooting situation. A customisable AFL button can be assigned to preferred functions via the camera menu, with further configuration available for L-Mount users through the SIGMA UD-11 USB Dock.
An aperture control ring allows for intuitive exposure adjustment directly on the lens, complete with click/de-click and lock switches for flexible operation during both stills and video work.
The robust, dust- and splash-resistant structure, along with a water- and oil-repellent coating on the front element, ensures reliability even in harsh outdoor environments. A dedicated petal-shaped hood with a secure locking mechanism is also included for added protection and convenience.
