Sigma 24-35mm f2 Art DG HSM Lens - Canon EF Mount
The Sigma 24-35mm f2 DG HSM Art lens is the world's first large aperture full-frame wide-angle lens offering a bright f/2.0 aperture throughout the zoom range. It allows photographers to carry one lens to do the work of three fixed focal length lenses, a 24mm, 28mm and 35mm - with f2 brightness and top optical performance. Premium FLD glass, with performance equal to flourite, and seven SLD glass elements allow for outstanding image quality. An updated AF algorithm makes for smooth, accurate and fast autofocusing while multi-layer coating control flare and ghosting.
