Sigma 70mm f/2.8 DG Macro Art Lens for Canon EF

Optimized for notable image clarity at close working distances, the Canon EF-mount 70mm f/2.8 DG Macro Art Lens from Sigma is a true 1:1, life-size macro lens well-suited for close-up and macro subjects. As a member of the esteemed Art series of lenses, this short-telephoto prime is also distinguished by its sophisticated optical design that makes use of two FLD elements, two SLD elements, one anomalous partial dispersion/high refractive index element, and two aspherical elements to limit both chromatic and spherical aberrations for high clarity, sharpness, and color accuracy. A Super Multi-Layer Coating also enhances image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality. Benefitting the imaging assets is a coreless DC motor that offers quick and accurate autofocus performance along with full-time manual focus override. The physical design utilizes Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision. As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications. Short-telephoto prime, this lens is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 112mm equivalent focal length. Two F Low Dispersion (FLD) elements, two Special Low Dispersion (SLD) elements, and one anomalous partial dispersion/high refractive index element are featured in the optical design, and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy. Two aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.
