Superior Bokeh and Depth of Field
Dreamy background blur for artistic portraits
With its large F1.2 aperture and 13-blade rounded diaphragm, this lens produces an ultra-smooth bokeh effect. The shallow depth of field helps subjects stand out beautifully against soft, blurred backgrounds, perfect for portrait and creative photography.

Maximum Aperture for F1.2 Brightness
The SIGMA 50mm F1.2 DG DN Art Lens produces a beautiful bokeh expression. This is a result of the contrast between the focus surface area’s sharpness and the melting bokeh effect, which results in a three-dimensional effect. The lens’ 13-blade diaphragm captures breathtakingly beautiful bokeh expressions. The suppressed focus breathing lets the photographer utilize F1.2 to its optimum level during video recording. The optical design of this E-Mount lens reduces aberration and minimizes color bleeding to give you accurate images. It gets rid of spherical aberration, sagittal coma flare, axial chromatic aberration, and other aberrations. The results are beautiful Bokeh images with minimal color bleeding. The floating focus capability of the SIGMA 50mm F1.2 DG DN Art Lens improves short-range shooting, resulting in stable images of high quality through an entire range. The SIGMA Art lens suppresses double-line bokeh to give a mellow bokeh effect.
13-Blade Rounded Diaphragm
A first-of-its-kind, the SIGMA lens’ 13-blade diaphragm keeps a circular shape intact even at maximum aperture. The aspherical lens’ surface accuracy is enhanced to achieve smooth and round bokeh expressions.
Minimal Focus Breathing
When shooting videos, the SIGMA lens’ change in angle of view is so minimal that it maintains a natural-looking shift. This minimized-focus breathing is possible due to its focus group arrangement and aspherical shape.
Reduced Flare and Ghosting
Experience minimal flare and ghosting in the images with this 50mm Art lens. The backlight resistance capability of this lens enables the photographer to capture sharp pictures even in the most dimly lit conditions.
Lightweight Lens Body
The lightest lens body in its class, the SIGMA 50mm F1.2 DG DN Art Lens, is a versatile lens that can be used across a range of photography styles in unique shooting conditions.
HLA System
The lens’ HLA system reduces volume despite maintaining the usual thrust of the HLA, which helps to achieve accuracy without noise. This technological advancement helps achieve high-speed autofocus for a compact lens body.
Lens Construction
The glass construction of this lens is made to be as thin as possible, boasting a high refractive index. SIGMA's only manufacturing base at Aizu, Japan, provides accurate information about these thin glasses, allowing mass production without compromising on quality. The floating focus of the lens allows high performance at a shorter length, which helps to give this art lens a compact design.
Durable Build
The SIGMA 50mm Art Lens features an AFL button and an aperture ring for advanced photography. Its body is built of high-quality and strong components like TSC that render a premium touch and feel. Designed to meet the high functionality and demands of modern-day professionals, the long-lasting durability of this lens is a testament to the brand’s credibility.
Shooting Assistance
With a range of shooting assistance functions like the AFL button or the aperture ring, the SIGMA 50mm Art Lens allows a range of versatile shooting options. The aperture ring features an aperture ring lock switch and a click switch. This allows clicking on and off easily. The lens features dust and splash resistance on the front element and has a water- and oil-repellent coating. Such additional features enable photographers to shoot in any environmental condition without worry.
