Compact 50mm. Big Surprise.
Performance beyond expectations condensed into a small body.
50mm F2 joins the “Premium Compact Prime" I series.
The SIGMA 50mm F2 DG DN | Contemporary features high optical performance with a bright F2 aperture, that creates expressive images with a shallow depth of field and beautiful bokeh effects. With its compact size, this popular classic focal length is perfect for portraits, street and everyday photography. The lens has been designed to be used over a long period of time. Using that same technology that SIGMA used to create the SIGMA CINE lens range, the 50mm F2 DG DN | Contemporary uses an all-metal construct that is robust and provides a premium feel.
All these elements combine to create an exceptionally versatile lens that can be used in a variety of creative ways to create images in outstanding definition. Perfectly suited to new photographers looking to take the next step, professionals who require reliable lenses and photographers who prefer smaller full-frame lenses that offer the best optical quality.

Features
“Standard lens” that matches the optical performance standards set by the SIGMA Contemporary line of lenses.
SIGMA I series lenses are developed around the concept of “Compact everyday lenses with outstanding image quality” and the SIGMA 50mm F2 DG DN | Contemporary is exactly that. It features high-quality optics in a compact size, perfect for a wide variety of photographic styles. Built from the ground up for mirrorless cameras, the SIGMA 50mm F2 DG DN | Contemporary is constructed using a single SLD glass element and three aspherical lens elements that are excellent at correcting various types of aberration for clear, high-definition images.
The conflicting ideals of improving optical performance while reducing body size and weight are achieved through the latest optical design, and the processing and production technologies at SIGMA’s only production facility in Aizu.
The 50mm focal length is mostly known for portrait photography, so careful consideration was taken when designing the lens, focusing on the smoothness of the bokeh created by the F2 aperture. Its optical design gives smooth transitions from in-focus to out-of-focus areas, and helps minimize flare and ghosting caused by backlit environments. The quiet stepping motor provides quick, reliable autofocusing for both stills and video.
Expanding the I series lineup.
“Creating pictures that are beyond beautiful”.
The SIGMA I series features full-frame compatible lenses that offer new value to mirrorless systems. The combination of superb optical performance with a level of compactness that is perfectly suited to smaller and lighter modern mirrorless cameras will bring you new opportunities for a perfect shot. SIGMA is aware that in today’s world we have a wide range of camera choices, especially with the increase in mobile phone ownership. But with many photographers looking for something more than something that simply captures images when they choose to own a camera and lens, I series lenses offer the ultimate combination of superb optical performance, outstanding usability and compact form-factor. SIGMA’s excellence in development and production technologies has been built up since our founding in 1961 and became increasingly sophisticated with the introduction of the SIGMA Global Vision brand in 2012. With this as a base, SIGMA has given careful thought to the quality of the products, the feeling of using it and the pleasure of owning it. This is how the I series was born.
Exceptional I series build quality with a compact form-factor
All I series lenses have an all-metal construction. The precision-cut aluminum parts not only give the barrel a sleek, stylish finish, but provide superb durability that improves the quality of the entire product. Metal materials are also used in internal structures that slide with the operation ring for added robustness. These high-precision components crafted with SIGMA’s cutting-edge metalworking technology are also used in SIGMA’s CINE LENS lineup for professional cinematographers and provide a tactile, ergonomic feel that make the lens a pleasure to use.
A smooth hairline cover ring is used between the focus and aperture rings to act as a finger hold when attaching and detaching the lens.
Magnetic metal lens cap
I series lenses are accompanied by a dedicated magnetic metal lens cap*, in addition to a normal plastic cap. This dedicated metal cap clips to the front surface of the lens magnetically. It is no exaggeration to say that this meticulously crafted cap represents the finishing touch for the I series.
*Except SIGMA 45mm F2.8 DG DN | Contemporary
※ The image is 35mm
※ Cannot be used when a filter is attached.
Magnetic metal lens cap holder
LENS CAP HOLDER CH-11 (sold separately)
When a cap is removed from the lens it should have a proper place where it can be kept. Using this as a starting point, a cap holder using the magnetic force of the dedicated cap was created.
With the cap attached to the ring plate, and the plate clipped to a bag or belt, the cap is always within easy reach and is less likely to get lost. Plus, its elegant design is a stylish addition to a photographer’s equipment.
