The technical details behind this lens
Sigma 20mm f/1.4 DG HSM Art Series Lens - Canon offers great performance. The wide focal length and consistent image quality make this lens well-suited for interior, landscape, architectural, and astrophotography applications, while the fast f/1.4 maximum aperture deems it great for natural and low-light shooting. The lens's optical design comprised 15 elements in 11 groups. The lens design uses two "F" Low Dispersion (FLD) elements, five Special Low Dispersion (SLD) elements, and two aspherical elements to reduce chromatic and spherical aberrations, as well as limit distortion for clean, sharp and evenly illuminated imagery. Featuring Super Multi-Layer Coating, It has been applied to minimise surface reflections, flare, and ghost effects for enhanced contrast and colour accuracy. The Sigma 20mm f/1.4 DG HSM Art Series Lens - Canon is a member of the venerable Art series of Global Vision lenses from Sigma and pairs a sophisticated optical design with robust physical construction. This lens also features a rounded nine-blade diaphragm that helps to achieve an attractive out-of-focus quality.
Integrated Hyper Sonic Motor (HSM)
This feature realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to achieve smoother focusing performance. The Hyper Sonic Motor allows full-time manual focus control simply by rotating the focus ring at any given moment.
Super Multi-Layer Coating
Applied to lens elements in order to reduce lens flare and ghost effects and contribute to producing contrast-rich and colour-neutral imagery, even in backlit conditions.
