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 Sony E-Mount Mirrorless Camera. 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.
Hyper Sonic Motor Ensures High AF Speed
The Hyper Sonic Motor (HSM) ensures silent, high-speed autofocusing, while the optimized AF algorithm helps realize even smoother AF performance. At any time during AF, users may access MF simply by rotating the focus ring. This feature makes faster focus adjustment possible, since there is no need to use the AF/MF focus mode switch.
Note: The operation of full-time MF may vary based on mount type.
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 Sony E 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 Sony has a native Sony E-mount that 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 Sony E-mount digital cameras, this high-performance lens delivers outstanding resolution and high-clarity image quality even at wide-open aperture.
