The First Macro Lens in the Sigma Global Vision Art Line

To achieve optimal results at every shooting distance, the lens features an extending, floating, two-group focus mechanism, which minimizes aberration at all focal lengths. In addition, the lens’ optical elements design increases resolution at close shooting distances, allowing for a razor-sharp in-focus area contrasted with a bokeh area free of color streaking.
Other feature highlights include focus-by-wire system featuring newly developed coreless DC motor for comfortable and precise focusing typically required for macro photography; compatibility with full-frame Sony E-mount camera systems; compatibility of the Canon mount lens with the Canon Lens Aberration Correction function; and compatibility with Sigma Electronic Flash Macro EM-140 DG and Sigma Teleconverters.
