Splendid architectural and landscape shot can be taken with the Sigma 14-24mm f/2.8 DG HSM Art Lens. It’s an ultra-wide zoom lens compatible with full-frame Canon EF cameras. The lens comprises of three Fluorite Low Dispersion (FLD), three Special Low Dispersion (SLD), and three aspherical elements that minimize color fringing and chromatic aberrations for better image quality. Contrast-rich and color-neutral visuals can be created even in backlit conditions, thanks to its Super Multi-Layer Coating. You can also achieve a smoothly rounded bokeh with the nine-blade diaphragm. The integrated Hyper Sonic Motor ensures quiet and high-speed autofocusing that permits full-time manual focusing control. The durable brass bayonet mount protects and keeps the lens clear of water and dust.
