Sigma Art 20mm f/1.4 DG DN 20mm
This 20mm f/1.4 prime is the world's first of its kind for full-frame, using 15 elements with two aspherical and five ED glass to deliver edge-to-edge sharpness at the bright aperture. Silent, high-speed Hypersonic AF and robust ART-series build quality make it reliable for precise focusing in challenging light. It’s best for astrophotographers and low-light event shooters who prioritize aperture over portability, though its 948g heft rules it out for travel.
