Description
The Sigma 70mm f2.8 DG Macro Art Lens is the first macro lens in the art line offering its users top-level performance at every shooting distance thanks to the incorporation of an extending, floating, two-group focus mechanism. The optical system utilises two FLD glass elements, two SLD glass elements, and one element featuring a high rate of anomalous partial dispersion in addition to high index of refraction. Combined these elements minimise axial chromatic aberration. The resolution has been increased at close shooting distances thanks to the two aspherical lens elements. In addition to this the user can achieve razor-sharp in-focus area which contrasts with a bokeh area free of colour streaking.
