A classic focal length perfect for portraits
A classic focal length now available as a SIGMA I series lens. The SIGMA 50mm F2 DG DN | Contemporary is a versatile lens for enthusiast and professional photographers and available in L-Mount and Sony E-mount. Create portraits with beautiful bokeh and effortlessly capture your surrounding when shooting street photography, all in stunning detail thanks to the high-quality optics that effectively minimise aberrations. Its weight of 350g and compact size are ideal for travelling.
Versatile F2 maximum aperture
The lens features a wide F2 aperture, able to create true-to-life portraits with beautiful bokeh effects, and with its compact size and weight of 350g, the lens is the perfect photography tool for travel and street photography. Constructed using high-quality SLD and aspherical glass elements, the lens is an excellent upgrade for photography enthusiasts who want to improve the quality of their existing 50mm lens and for professionals who prefer smaller camera systems without compromising on image quality. The glass elements also effectively minimise flare and ghosting in back-lit environments.
Feature rich and customisable
Easily control the amount of light entering the lens and the depth-of-field using the aperture ring. The lens also features Direct Manual Focus (DMF) and a focus mode switch, and supports switching between non-linear and linear focusing when customised using the SIGMA USB DOCK UD-11 (sold separately / for L-Mount only). It is also compatible with AF assist functions found on compatible cameras (E-mount only).
A robust and compact lens designed for travel
A dust- and splash-proof mount is fitted to help stop contamination from dust and water. The tactile knurled metal lens hood, focus ring and aperture ring improve the grip on the lens for greater control when in unique situations such as mountaineering.
Between the aperture and focus ring is a covering that helps finger placement when attaching and detaching the lens. It uses hairline processing for a sleek and stylish finish. Included with the lens is a magnetic metal lens cap which further improves ease of use.

Essentials
You'll find our philosophy and craftsmanship in every product
Our lens line-up fully expresses our approach to lenses and photography itself. All of our lenses belong to one of three lines—Contemporary, Art or Sports—all of which share our development philosophy and advanced manufacturing system. High performance, high quality and high end in every respect, these lenses give people who love photography lasting value and consistent, exciting results. The secret is our passion for craftsmanship that we put into every production process and every product.
Evaluation with Sigma's own MTF measuring system “A1”
We used to measure lens performance with MTF measuring system using conventional sensors. However, we’ve now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections.
