overview
Click sharp close-up shots with the Sigma 70mm f/2.8 DG Macro Art Lens. Compatible with Sony E-mount cameras, the lens has 13 elements in 10 groups. There are two FLD and two SLD elements, a single high refractive index element, and two aspherical elements to correct chromatic and spherical distortions. The Super Multi-Layer Coating offer clarity by reducing flare and ghosting. This Sigma lens houses a coreless DC motor that also allows manual focus override. The large angle of rotation and a focus-by-wire system contribute to the focusing work. The 9-blade diaphragm provides a circular bokeh effect in the blurred background. The Thermally Stable Composite material construction ensures safety of the lens at extreme temperatures. You may fix optional TC-1401 and TC-2001 teleconverters to the lens for extending its focal length. The Sigma USB Dock compatibility allows you to adjust the focus parameters and update the firmware.
