The Sigma 105mm F2.8 DG DN MACRO Art is a mid-telephoto prime lens engineered specifically for full-frame Sony E-mount mirrorless cameras, delivering exceptional optical performance for both macro and portrait work. With a 1:1 magnification ratio and minimum focusing distance of 11.6 inches, this lens enables true macro reproduction of life-size subjects while offering versatile working distance for professional-grade results. Its advanced optical design features 17 elements in 12 groups, including one Super-Low Dispersion element that effectively suppresses chromatic aberrations and longitudinal fringing across the entire focus range. The quiet, fast Hyper-Sonic Motor (HSM) delivers precise autofocus with full-time manual override, whilst the de-clickable aperture ring and customisable AFL button provide intuitive controls for photographers. Built with a dust- and splash-proof structure, this Art-line lens prioritises edge-to-edge sharpness, superior contrast through Super Multi-Layer Coating, and smooth bokeh rendition via its 9-blade diaphragm.
