Product Specifications

Basic Information

Product Features

A 50mm F2 lens joins the lineup of the “Premium Compact Prime” I-series lenses.

The SIGMA 50mm F2 DG DN Contemporary, with a focal length of 50mm, is one of the most popular standard lenses, featuring high optical performance and a large, beautiful bokeh effect, and combining expressive power that can be enjoyed in any situation with compactness that allows it to be carried anywhere.
And the all-metal body, a distinctive feature of the I-series, provides the satisfaction of lens ownership and robustness backed by the technology of film-use lenses. Because it is a basic focal length, we want a product that can be used for a long time. With this in mind, we pursue performance and durability beyond expectations. This lens, which brings together the balance of each element at a high level, is one that is worth picking up, whether you are looking for your first interchangeable lens or you are a seasoned professional.
The lens body is compact and exquisitely finished in relation to the high definition and soft bokeh that only a bright full-size lens can produce, and its performance. You will be amazed at the gap between the two.

1. “Standard lenses” that set a new standard for optical performance in the Contemporary line
The I-series lenses were developed based on the concept of “premium compact prime” lenses that offer high performance and are compact and lightweight.
The 50mm F2 DG DN Contemporary also offers surprisingly high optical performance and expressiveness for such a compact size.
The lens construction features a single SLD glass element and three aspherical lens elements, which provide excellent correction of various types of aberrations. The lens construction features one SLD glass element and three aspherical lens elements to compensate for various aberrations and deliver clear, high-definition images. The contradictory 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, Japan. In terms of expressiveness, Sigma also pursues beautiful bokeh. Considering that this focal length is often used for portrait photography, we focused on the softness of the bokeh itself as well as the smoothness of the bokeh from the in-focus area to the out-of-focus area. A quiet and high-speed stepping motor is used for the AF drive system. The AF drivetrain uses a quiet and fast stepping motor to provide a comfortable shooting experience with quick autofocusing.

2. The I-Series offers more than just “beautiful images
The I Series is a series of full-frame compatible lenses that offers new value to mirrorless systems. One of the major advantages of mirrorless systems is that they are compact and lightweight. The combination of high optical performance and compactness that could not be achieved with SLR cameras also creates new shutter opportunities. SIGMA believes that, in this age of mobile devices and other means of photography, owning a camera and lenses is required to have more value than simply “taking pictures. The “I-series” lenses are the result of our deliberations, based on the high level of development and processing technology that we have accumulated since our founding in 1961 and refined through the SIGMA GLOBAL VISION in 2012, and the quality as a tool, the feeling of handling, and the joy of ownership itself. SIGMA Contemporary's answer to the question of what value can be proposed for the existence of lenses today.

3. build quality to I-series specifications
The metal exterior of the I-series common specifications is used. Parts made of machined aluminum are not only beautiful, but also enhance the quality of the product itself, such as its solid rigidity and high durability. Metal is also used for the internal structure that slides against the control ring. High-precision parts made possible by the advanced metalworking technology behind the “SIGMA CINELENS” professional-use lenses dedicated to imaging, provide each control part with a superb quality that makes you want to operate it over and over again. The cover ring placed between the focus ring and aperture ring has a hairline finish, which is also used on the rear barrel of the Art line. The cover ring gives the lens its own expression and also functions as a finger ring when attaching and detaching the lens.
