Sigma 12-24mm f/4 DG HSM | Art - Sigma SA, Nikon F, Canon EF Mount

The Sigma 12-24mm f/4 DG HSM Art is an ultra-wide-angle zoom designed for full-frame DSLRs, notable for its minimal distortion despite the expansive field of view. Featuring the largest aspherical glass element in its class at the time of release, it provides excellent corner-to-corner sharpness. The f/4 constant aperture and weather-sealed construction make it a robust choice for architectural and landscape photography. Due to the large, bulbous front element, the glass is vulnerable; inspect it carefully for any marks or coating damage, as standard filters cannot be used. Check the integrated lens hood for cracks. SDS verifies the HSM autofocus performance and performs a thorough optical check to ensure the complex internal assembly is perfectly centred and free from tilt.
