70mm f/2.8 DG Macro Art Lens (Sony E)

The Sigma 70mm f/2.8 DG Macro Art Lens for Sony E-mount is a true 1:1 macro lens optimized for close-up photography with a minimum focusing distance of 10.2 inches and life-size magnification. The optical design incorporates two FLD elements, two SLD elements, one anomalous partial dispersion element, and two aspherical elements that work together to minimize chromatic and spherical aberrations while delivering sharp, color-accurate imagery. A Super Multi-Layer Coating reduces lens flare and ghosting, while the rounded nine-blade diaphragm produces smooth, pleasing bokeh.

The lens features a coreless DC autofocus motor with full-time manual focus override for precise focusing control on macro subjects. The construction uses Thermally Stable Composite material combined with a brass bayonet mount that is dust- and splash-resistant, providing durability across varying environmental conditions and temperature ranges.
