14mm · f/1.8
The Sigma 14mm F1.8 DG HSM Art (L-mount) is optically excellent, offering extreme sharpness and minimal distortion, making it ideal for astrophotography and landscapes. Its f/1.8 aperture is unique for a 14mm prime, but field curvature is noticeable. Build quality is superb, with weather sealing and a solid feel, though the lens is heavy at ~1170g and lacks filter threads. Autofocus is quick and accurate. It suits photographers who need ultra-wide, fast aperture performance and are willing to accept the weight and cost.
