Sigma 50mm f/1.2 DG DN Art, model A024, is a standard prime lens designed for full-frame mirrorless cameras and available for Sony E and L-Mount. Its f/1.2 maximum aperture allows shooting with very shallow depth of field and in low-light conditions, making it suitable for portraiture, reportage, wedding photography, events, street photography, and video production. The optical design consists of 17 elements in 12 groups, including four aspherical elements, and has been developed to maintain high resolution from maximum aperture and throughout the focusing range. The diaphragm uses 13 rounded blades, designed to provide smooth out-of-focus rendering and more circular aperture shapes when stopping down. The autofocus system uses an HLA linear motor together with a floating focus configuration, with particular attention to speed, accuracy, and reduced focus breathing during video recording. The minimum focusing distance is 40 cm, with a maximum magnification ratio of 1:6.2 and a 72 mm filter thread. The lens includes an aperture ring with click/de-click operation, aperture ring lock, programmable AFL button, and AF/MF selector. The construction is dust- and splash-resistant, while the front element features a water- and oil-repellent coating. The L-Mount version measures approximately 81 × 108.8 mm and weighs 745 g, while the Sony E version measures about 81 × 110.8 mm and weighs 740 g. Sigma 50mm f/1.2 DG DN Art is suitable for photographers and videographers looking for an exceptionally fast autofocus 50 mm lens with strong subject separation and a relatively compact design for the f/1.2 class.
