Product Features
- High optical performance, build quality, and fun in a compact body! 20mm F2 ultra-wide-angle single focal length lens added to the I-series lineup
The 20mm F2 DG DN Contemporary combines the brightness of a maximum aperture of 2.0 and high optical performance in a compact body to create a new value for interchangeable lenses in the mirrorless era. To take full advantage of the 20mm's wide angle of view, we thoroughly pursued high resolution and uniformity from the center to the periphery of the image. The powerful expression of the strong perspective of the ultra-wide angle can be fully enjoyed across the entire image. The brightness of F2 also allows the lens to be used not only for landscapes and snapshots, but also for starry landscapes, which demand the highest optical performance. The compact shooting system makes it possible to take photos with ease and comfort. The satisfaction and attachment to the lens as a tool, backed by uncompromising image quality and meticulous build quality. The 20mm F2 DG DN Contemporary is the essence of the I-Series, bringing new value to the experience of owning and operating a lens.
- Premium Compact Prime" I-Series
The I-series is a series of full-frame compatible lenses that offers new value to mirrorless systems.
The compactness and light weight of a photographic system is one of the major advantages of mirrorless systems. The combination of high optical performance and compactness that could not be achieved with SLR cameras also creates new shutter opportunities.
On the other hand, Sigma believes that in this day and age, when the means of photography have become so diverse, including mobile devices, owning a camera and lenses requires more than just the act of "taking a picture.
The "I-series" lenses are the result of careful consideration of the quality of the lens as a tool, the feel of the lens when handling it, and the pleasure of owning it, all based on the high development and processing technologies accumulated since the company's founding in 1961 and refined through the SIGMA GLOBAL VISION in 2012. The answer from SIGMA Contemporary is to ask what kind of value can be proposed for the existence of lenses today.
- The Contemporary line: a new standard in optical performance
The 20mm F2 DG DN Contemporary achieves the highest level of optical performance at a maximum aperture of 2.0 from the center to the periphery of the image. Based on the latest optical design technology, the lens construction consists of three high-precision glass-molded aspherical lenses, one SLD glass element, and one FLD glass element to suppress aberrations to a high degree. This enables clear and sharp images from all corners of a wide angle of view. In addition, the lens focuses on suppressing sagittal coma flare, which is difficult to correct in post-processing, to achieve a high level of point image reproducibility. This allows for detailed rendering of night and starry night scenes across the entire image area. In addition to a design that takes flare and ghosting into consideration, the lens features Super Multi-Layer Coating and Nano-Porous Coating (NPC). The lens is suitable for all kinds of shooting situations thanks to its excellent backlight resistance.
- 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 CINE LENS, a professional-use lens designed exclusively for imaging, give each control unit a superb quality that makes you want to operate it again and 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.
