With a focal length of 20mm and this F1.4 aperture, it offers exceptional brightness and bokeh for an unprecedented visual experience.

SIGMA has a wealth of experience that draws on exemplary design know-how and cutting-edge technologies to develop high-aperture fixed-focus lenses that exploit the full potential of high-resolution SLRs. For its latest opus in this series, SIGMA has created an F1.4 ultra-wide aperture lens. With a focal length of 20mm and this F1.4 aperture, it offers exceptional brightness and bokeh for an unprecedented visual experience. By offering the photographer the perspectives of the wide angle and depth of field of the large aperture, this lens is ideal not only for subjects with a wide field of view such as landscapes and starry skies, but also for low-level photographs. light, indoor photography, portraits with a very natural bokeh effect, and many other subjects.

A level of performance adapted to the very high resolution

At the beginning of the film era, there were very few ultra-sensitive films, and bright lenses were essential for maintaining "high speed" in low light conditions. These lenses are ideal for indoor, late-night, under cloudy, or low light photography. By offering the benefits of an ultra wide angle lens with minimal distortion the SIGMA 20mm F1.4 DG HSM I Art is ideal for photographing landscapes with starry skies and architecture. While allowing you to capture classic wide-angle images with all the sharp shots, the photographer can exploit the very large aperture to clear the subject and generate a blurry background, with a very attractive bokeh effect
Minimal chromatic aberrations

This objective minimizes the chromatic aberrations that are common in bright, wide-angle lenses. It features two FLD ("F" Low Dispersion) * glass elements and five SLD (Special Low Dispersion) glass elements to reduce lateral chromatic aberration, which appears especially around the image periphery. The optical formula helps to minimize axial chromatic aberration. The result is a high picture quality in all circumstances, without colored fringes and with a high level of contrast.
Minimal distortion

Distortion is common in wide angle lenses. It is from the initial design phase that it must be mastered. With the right angle of light incident on the first lens and the judicious use of aspherical elements, the SIGMA 20mm F1.4 DG HSM | Art minimizes distortion on the entire field of the image.
