overview

The Sigma 70mm f/2.8 DG Macro Art Lens deserves a place in your camera kit. It can be used with Sigma SA-mount cameras. The lens design comprises 13 elements in 10 groups. It includes two FLD and SLD elements along with a single high refractive index element to combat chromatic aberrations. Two aspherical elements reduce the effects of spherical distortions to improve clarity. The Super Multi-Layer Coating minimizes lens flare and ghosting. With the coreless DC motor, the lens remains silent when autofocusing on an object from a minimum distance of 25.8 cm. The autofocus override option lets you fine-tune the focus in the auto mode. Also, the large angle of rotation and a focus-by-wire system make focusing work easier. The 9-blade diaphragm produces a circular bokeh effect to improve the shallow depth of field. The Thermally Stable Composite material construction enables the lens to work at extreme temperatures. Optional teleconverters such as the TC-1401 and TC-2001 can be attached to this lens. This telephoto lens is compatible with the Sigma USB Dock to adjust the focus parameters and update the firmware.

Lens Magnification Factor: 1.0x
Lens Magnification Factor:
This is the magnifying factor of a lens. Macro lenses will often be described by their “magnification factor”. A lens with a 1:1 magnification factor produces a projected image on the sensor which is the same as the subject.

Elements / Groups: 13 / 10
Elements / Groups:
The individual pieces of glass that form the overall optical construction. Most lenses have between four and eleven elements to bend the light rays to ensure a perfectly formed image appears on the light sensitive surface, such as a film or CCD. The elements are arranged in groups and may be seen in specification sheets as, for example, 6 elements in 4 groups. That configuration may have two single elements and the other four grouped in pairs.
