Sigma 20mm f/1.4 DG HSM Art Lens for Sony E

The Sigma 20mm 1.4 DG HSM Art is a state of the art wide-angle prime lens designed for Full Frame cameras but will work with APS-C sensors as well. Using over 50 years of lens making experience and the knowledge gained from the 35mm 1.4 Art and the 24mm 1.4 Art, the 20mm 1.4 Art is the widest large aperture Art lens. The latest optical design allows for the utmost in image quality with careful attention paid to edge to edge performance. Through decades of experience in lens design and Sigma Global Vision lens manufacturing, the 20mm incorporates both Low Dispersion (FLD) glass, and five Special Low Dispersion (SLD) glass in a design of 15 elements in 11 groups. The combination of advanced optics and optimized lens power distribution minimizes spherical aberration, axial chromatic aberration and field curvature, producing outstanding image quality. With class leading performance, this lens is ideal for landscape photography, videography, astrophotography, lowlight/indoor photography and event photography.

Compatible with In-Camera Image Stabilization

Compatible with in-camera image stabilization, the camera automatically detects the focal length of each lens and optimizes image stabilization performance.

Data Pre-Loaded for Compatibility with In-Camera Aberration Correction

Fully compatible with in-camera aberration correction (corrections for peripheral illumination, chromatic aberrations, and distortion). By matching corrections to the optical characteristics of the lens, this function takes image quality to an even higher level.

Native Mount for a More Rigid and Stable Feel

Making the lens mount native provides a much more rigid and stable feel to the lens than using an adapter. Featuring a surface treatment to enhance strength, the brass bayonet mount offers a high-precision fit and exceptional durability. The mount connection area incorporates rubber sealing for dust- and splash-proof construction.

Available SIGMA Mount Conversion Service

This service converts specifications of the mount of SIGMA lenses to that of a different camera body. Users can "tailor" their favorite lenses to the camera body if they plan to get a new one in the future. This allows continued use of their favorite lenses over the long term regardless of the camera system.

Art Lens

Engineered for those who see photography as a critical expression of self, Sigma's Art line offers sophisticated optical performance and abundant expressive power to deliver faithfully on your artistic vision.

DG for Digital

Designed to deliver the ultimate in performance on full-frame digital SLRs, Sigma DG lenses also bring out the best in 35mm SLR film cameras and APS-C size DLSRs.

Aspherical Lens Elements (ASP)

The aspherical lens complex allows freedom of design, improved performance, a reduced number of component lenses and a compact size.

Hyper Sonic Motor Focusing (HSM)

HSM lenses employ a motor powered by ultrasonic waves that produce a quiet, yet high-speed AutoFocus. You can enjoy high performance with low noise in a variety of shooting situations.

Inner Focus (IF)

To ensure stability in focusing, this lens moves the inner lens group(s) without changing the lens' physical length.

20mm Ultra-Wide-Angle and F1.4 Brightness

To offer an ultra-wide-angle 20mm focal length and F1.4 brightness at wide-open aperture, this lens 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.
