Peak Design
The Sigma 70mm f/2.8 DG Macro Art Lens is a true 1:1, life-size macro lens that has been designed for notable image clarity at close working distances. This short telephoto prime features a 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 has also been applied to enhance image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions. It also features a rounded nine-blade diaphragm for a pleasing bokeh quality effect.
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.
