Overview

The Sigma 14mm F1.8 Art is an ultra-wide-angle lens with a unique f/1.8 aperture, ideal for astrophotography and landscapes. It delivers excellent sharpness and minimal distortion. However, it exhibits noticeable field curvature. Build quality is robust, with weather sealing and a solid feel, but it is heavy at over 1kg. Autofocus is quick and accurate. Best suited for astrophotographers and those needing a fast ultra-wide, despite its weight and price (AlynWallace).
