The Sigma 20mm f/1.4 DG HSM Art (Nikon Mount) is an ultra-wide, fast-aperture prime lens designed for full-frame Nikon DSLR cameras. Ideal for landscapes, astrophotography, architecture, and low-light shooting, it delivers exceptional edge-to-edge sharpness and minimal distortion. Built with Sigma’s Art line optical design, it features FLD, SLD, and aspherical elements for superior clarity and contrast. The f/1.4 aperture provides beautiful background separation and smooth bokeh, while the Hyper Sonic Motor (HSM) ensures fast, quiet autofocus with full-time manual focus override.
