The World’s First F1.4 Ultra-Wide-Angle Lens
Advanced Technologies Make This 
20mm F1.4 Lens Possible

The SIGMA 20mm F1.4 DG HSM | Art lens for Nikon incorporates a large double aspherical lens 59mm in diameter. Lenses of this type had been considered extremely difficult to manufacture, but SIGMA took on the challenge to realize an F1.4 ultra-wide-angle lens that fulfills the strict performance requirements of the SIGMA Art line.

Ideal High-Speed Lens With Top-level
Performance For The Ultra-High-Megapixel Era

The SIGMA 20mm F1.4 DG HSM | Art Lens for Nikon provides the benefits of an ultra-wide angle lens with minimal distortion, it is ideal for photographing landscapes, starry skies, and architecture. In addition to capturing wide-angle shots with the whole scene in focus, the photographer can leverage wide-open aperture to take snapshots with the subject in focus and the background blurred with an attractive bokeh effect. Designed for ultra-high-megapixel Nikon digital cameras, this high-performance lens delivers outstanding resolution and high-clarity image quality even at wide-open aperture.

Incredible Rendering Performance Delivers Unprecedented Visual Experiences.
Enjoy Enhanced Control Of Light And Composition.

SIGMA has extensive experience in leveraging its advanced design capabilities and leading-edge technologies to craft large-aperture prime lenses that bring out the full potential of ultra-high-megapixel Nikon DSLRs. As its latest achievement in this category, SIGMA has created an ultra-wide-angle lens with F1.4 brightness. With a focal length of 20mm and F1.4 aperture, this lens delivers outstanding large-aperture brightness and bokeh, delivering unprecedented visual experiences. Allowing the photographer to leverage the perspective provided by the wide -angle and the shallow depth of field provided by the large aperture, this lens is ideal not only for such ultra-wide-angle subjects as landscapes and starry skies, but also for snapshots in low light, indoor photography, portraits with a natural bokeh effect, and much more.

Minimized Distortion

Distortion is a common issue in wide-angle lenses, and it is not possible to correct it simply by changing the aperture value. For this reason, a lens must be designed from the start to minimize this issue. By adjusting the incidence angle of light starting with the first lens element and incorporating optimally positioned aspherical glass elements, the SIGMA 20mm F1.4 DG HSM | Art lens for Nikon minimizes distortion throughout the entire image.
