Art was the first GLOBAL VISION lens and ushered in an era. It was launched in 2012 and set the standard for all subsequent lenses in the Art product line. Thanks to its exceptional image quality, it is still the 35mm fixed focal length of choice for many professional photographers. Now, after years, the 35mm F1.4 has been developed from the ground up - specifically for mirrorless cameras. n this new development culminates the lens development skills and advanced manufacturing techniques that SIGMA has gained over the past decade. Like all of its products, the 35mm F1.4 DG DN Art is produced entirely at the factory in Aizu, Japan, where the highest level of optomechanical manufacturing quality is assured. At the heart of the 35mm F1.4 DG DN Art's design was an optical calculus at the highest level in its class. Although it remains significantly smaller and lighter than the existing 35mm F1.4, it is sharp right to the corners of the frame at open aperture and produces a creamy background bokeh; all aberrations are well corrected.
