Sigma 20mm f/1.4 DG HSM Art Lens for Nikon F

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 a 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 a wide-open aperture.

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.

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.

A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality
