Designed for long exposures of night skies, the Sigma 14mm f1.4 DG Art is a full-frame ultra-wide prime that combines the Art line's premium optical design with a 114° field of view and a bright f1.4 aperture. Its coma-controlled optics keep stars tidy towards the edges, while the tripod socket, rear filter holder and heater retainer work together to make extended outdoor sessions steadier and easier to manage.
