This very wide Sigma 14-24mm F2.8 DG HSM Art zoom lens is an excellent option for architectural and landscape photographers cameras. As part of the acclaimed Art-series lenses, an advanced optical design is used that includes three Fluorite Low Dispersion (FLD), three Special Low Dispersion (SLD) and three aspherical elements to reduce chromatic aberrations and keep the distortion under control. A Super Multi-Layer coating is also used to suppress lens flare and ghosting for accurate color fidelity and high contrast.
This lens features a Hyper Sonic engine to deliver fast, smooth and quiet autofocus performance with permanent manual focus overrun. The lens has a rounded diaphragm with 9 blades that gives a smooth appearance to blurred areas and offers a minimum focusing distance of 26 cm. Finally, a weather-resistant copper bayonet mount helps keep water and dust away from your equipment when shooting in harsh conditions.
