Revisions to the lens include the inclusion of one Special Low Dispersion (SLD) glass element and four of the company’s new “F” Low Dispersion FLD glass elements to compensate for color aberration and provide high image quality. FLD glass is the highest level, low dispersion glass available with extremely high light transmission and performance equal to fluorite glass.

   

The Sigma 12-24mm F4 DG HSM Art is a premium full frame wide angle zoom designed to have minimal distortion in its wide angle imagery. Part of the Art line, the Sigma 12-24mm F4 DG HSM Art was created from decades of experience manufacturing wide-angle lenses. FLD glass elements, with performance equal to fluorite, provide for exceptional image quality while an updated Hyper Sonic Motor (HSM) uses 1.3X the torque for quick AF. A constant F4 aperture through the entire zoom range allows for greater ability in low light compared to previous models and the use of the largest aspherical element in the industry controls distortion, ghosting and flaring. An emphasis on edge to edge performance brings stunningly sharp and contrasty images to life. Ideal for many types of photography, the 12-24mm F4 Art is perfect for landscape photography, architecture photography, interior photography and much more.
