Sigma has announced the Sigma 14mm f/1.4 DG DN Art Lens, a full-frame ultra-wide-angle prime lens ideal for astrophotography. This is the widest F1.4 single focal length lens designed exclusively for mirrorless camera systems, and is available in Sony E-mount and Leica L-Mount.  This lens offers a full set of features designed for astrophotography including a removable tripod socket, MFL switch (Manual Focus Lock function), lens heater retainer, rear filter holder, and a specially-designed front cap including a new locking mechanism and new filter storage slots plus thorough aberration correction. Its ultra-wide 14mm angle of view and fast F1.4 aperture are ideal specifications for astrophotography. Sharp from corner to corner with splash and dust-resistant construction, this lens retains the same performance and quality standards found within the SIGMA F1.4 Art lens lineup. The lens will retail for $1,599 through authorized US retailers and will be available in late June 2023.
