With the introduction of this lens, Sigma's line of high-intensity wide-angle fixed focal length lenses, compatible with the full frame, will be expanded to five lenses from 14mm to 35mm. All lenses, except the 14mm lens, have a F1.4 light intensity (F1.8 at 14mm) and offer the photographer the choice of angle of view that fits well, an attractive bokeh and inspire his imagination. The 28mm image angle was often used in the era of analog cameras and still has many fans today. The Sigma 28mm F1.4 DG HSM | Art was developed to meet the wishes of many photographers who have expressed a strong interest in using the familiar 28mm image angle in the quality of the Art product line. Sigma was able to draw on its experience from the development of the previous Art-F1.4 fixed focal length lens product line. This new classic wide-angle lens, which benefits from the latest design, materials and processing technologies, is now part of Sigma's Art product line.
