The SIGMA 50mm F2 DG DN | Contemporary adds the classic standard prime lens focal length to the all-metal SIGMA "I series". This is the fifth F2 I series lens to date, joining the 20mm, 24mm, 35mm, and 65mm lenses. All F2 I series lenses feature an arc-type AF/MF switch and a stylized ring on the all-metal barrel. This DG DN lens is designed specifically for full-frame mirrorless systems.
The metal lens hood, manual-focus and aperture ring are knurled for pleasing tactile experience, and the F2 maximum aperture delivers pleasing bokeh effects; while the optical design delivers results comparable with the 50mm F1.4 DG DN | Art lens in a much more compact lens (37% shorter length, 48% less in weight.)
The lens also has minimal flare and is resistant to backlighting. AF is driven by a stepping motor for fast, reliable AF for both still and video use.
This is a best-in-class standard prime lens for everyday use, combining the exceptional I series build quality, strong optical performance and a compact, fast-aperture design.
Performance beyond expectations condensed into a small body
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.
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 line-up 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.
