Sigma has announced the 15mm f/1.4 DC Contemporary, a new fast, wide-angle lens for APS-C mirrorless cameras. The new lens is the successor to the beloved Sigma 16mm f/1.4 DC DN Contemporary lens unveiled way back in 2017. The Sigma 15mm f/1.4 DC Contemporary is the latest in a large series of fast APS-C prime Contemporary-series lenses, joining popular primes like the 12mm f/1.4 DC, 16mm f/1.4 DC DN, 23mm f/1.4 DC DN, 30mm f/1.4 DC DN, and 56mm f/1.4 DC DN. The 15mm f/1.4 DC Contemporary slots in just below the 16mm f/1.4 DC DN in terms of coverage, while promising a more compact, lighter wide-angle option for photographers and videographers. Compared to the Sigma 16mm f/1.4 DC DN Contemporary, the new 15mm f/1.4 DC Contemporary lens is approximately 30% shorter, about 50% lighter, and has a filter diameter that has shrunk from 67mm to just 58mm.…
